Born in Ljubljana, Dončić shone as a youth player for Union Olimpija before joining the youth academy of Real Madrid. In 2015 he made his debut for the academy's senior team at age 16, becoming the youngest in club history.
Dončić made his senior debut for Slovenia in 2016 at only 17 years of age. He would later help his country win its first EuroBasket title in 2017 while also being named to the All-Tournament Team.
According to his family, Dončić first touched a basketball when he was seven months old and frequently played with a miniature hoop in his room by age one. He played various sports in his childhood, including football, which he later quit after growing too tall. At age seven, he began playing organized basketball at a primary school in Ljubljana. His opponents at the time were up to ten years old, as Dončić reflected: "I was always training and playing with older kids who had much more experience than me. Many of them were bigger and faster than me too, so I had to beat them with my brain." He admired Greek basketball player Vassilis Spanoulis from his early teenage years, stating that he was "enchanted" by him. He wore the number 7 at Real Madrid in honor of Spanoulis. Dončić also grew up admiring American basketball player LeBron James.
When Dončić was eight, his father started playing for his hometown club Union Olimpija. Olimpija Basketball School coach Grega Brezovec invited Luka to practice with players his age. Dončić was initially expected to practice with players his age. Still, only 16 minutes into his first training session, the coaching staff moved him to the 11-year-old group. Starting in the next session, he primarily practiced with Olimpija's under-14 team. Still, due to league rules, he only played for the club's under-12 selection team, coming off the bench against opponents three or four years older than him. Despite his exclusion from under-14 games at the time, Dončić often asked to attend practice, even when his coach asked him to stay home.
Representing Olimpija at the under-14 Vasas Intesa Sanpaolo Cup in Budapest in September 2011, Dončić was named the most valuable player (MVP) despite finishing as runners-up to FC Barcelona. In February 2012, he was loaned to Spanish club Real Madrid for the Minicopa Endesa, an under-14 Spanish club competition. Dončić averaged 13.0 points, 4.0 rebounds, 2.8 assists, and 3.3 steals per game to win tournament MVP honors, leading Real Madrid to a second-place finish. In April 2012, he participated in the under-13 Lido di Roma Tournament for Olimpija, finishing as MVP and leading scorer with 34.5 points per game. In the semi-final round of the event against Victoria Fermo, he posted 29 points and 15 rebounds. In a title-clinching win over Lazio, he erupted for 54 points, 11 rebounds, and 10 assists.

He moved to Madrid, living with football and basketball prospects. In February 2013, Dončić led Real Madrid to a Minicopa Endesa win, averaging 24.5 points, 13 rebounds, 4 assists, and 6 steals per game. In the tournament's final game, he contributed 25 points, 16 rebounds, and 5 steals to defeat FC Barcelona and win MVP honors. In March, Dončić earned MVP accolades of the under-16 Spain Championship, scoring 25 points in a championship game win over the Gran Canaria youth team.
In the 2014–15 season, Dončić mainly played with Real Madrid's under-18 and reserve teams. He averaged 13.5 points, 5.9 rebounds, and 3.1 assists with the reserve team, helping them win Group B of the Liga EBA, the amateur fourth-division of Spanish basketball. By the end of the season, he earned all-league honorable mention accolades from the basketball website Eurobasket.com. In January 2015, Dončić won the under-18 Ciutat de L'Hospitalet Tournament and was selected to the All-Tournament Team, despite being two years younger than the rest of the team. On January 6, against the youth team of his former club Union Olimpija, he posted a double-double of 13 points, 13 rebounds, 4 assists, and 4 steals. In May 2015, he also won the under-18 Next Generation Tournament, for which he was selected MVP after helping defeat defending champions Crvena zvezda Belgrade in the final.

In Slovenia's 103–97 win over Latvia in the quarter-finals, he scored 27 points and grabbed 9 rebounds. He recorded 11 points, 12 rebounds, and 8 assists, in the 92–72 semi-final win over Spain. In the final, Slovenia won by a score of 93–85 over Serbia. He had 8 points and 7 rebounds, before falling out of the game, due to an injury, in the game's third quarter. Dončić was also named to the competition's All-Tournament Team, joining teammate Goran Dragić, who was voted the EuroBasket MVP.
In his Olympic debut on July 26, 2021, Dončić scored 48 points in a 118–100 victory over Argentina. His 48-point performance tied for the second-highest men's point total in a single game in Summer Olympics history and marked the most in a men's basketball debut. In the semi-final match-up versus France, Dončić posted the third triple-double in Olympic men's basketball history with 16 points, 10 rebounds, and 18 assists in a 90–89 loss. Also, it ended his 17-match winning streak from the senior national team debut back in 2017. Slovenia ended up losing the bronze medal match versus Australia 107–93. For his play during the tournament, Dončić was selected to the FIBA All-Star Five team, joining Patty Mills, Ricky Rubio, Kevin Durant, and Rudy Gobert as the five best players at the Games.
During the tournament's group stage, Dončić scored 47 points as he led Slovenia to the Round of 16 with a 88–82 victory over France, claiming the top spot in Group B. His 47-point performance was the second-highest scoring total in EuroBasket history. It was the most points scored by any player in EuroBasket history in the last 65 years. On September 10, he scored 35 points while beating Belgium 88–72 to advance to the quarter-finals. The game marked his third consecutive game scoring 30+ points, becoming the first player in tournament history in 30 years to do so. Slovenia was eventually upset by Poland 90–87 in the quarter-finals.
"[Dončić is] incredible with the ball for a big guy. He's unbelievable in pick and roll play. His court vision is already unbelievable. I couldn't believe what I saw from a 19/20-year-old. He's a good shooter when he has time and I think he's going to be great for [the Dallas Mavericks] for a long, long time... I could shoot a little bit but I never had the court vision... the savviness that he brings to the game... He's going to pick defenses apart and it's going to be fun to watch."
Since his early years with Real Madrid, Dončić was tabbed as one of Europe's premier talents, with Spanish newspaper Marca giving him the nickname "El Niño Maravilla" (The Wonder Boy). Entering the 2018 NBA draft, he was widely seen as one of the best and most accomplished European prospects of his generation.Slam magazine considered Dončić the "best international prospect ever," and sports website SB Nation called him "most accomplished NBA prospect in decades." An anonymous NBA veteran scouting executive said that his game was "leap years above anyone" in his draft class.
Dončić is versatile on the offensive end, displaying proficiency in shooting three-pointers, mid-range jump shots, floaters, and shots in the post. His basketball IQ, intangibles, and skills have been considered his primary assets, and he is seen as an elite facilitator, especially on the pick and roll. NBA and EuroLeague coach Ettore Messina called him "phenomenal, especially mentally" for his age. His lack of lateral quickness to stay in front of most NBA point guards and wings has been labeled one of his main flaws. Dallas Mavericks head coach Rick Carlisle refuted some of the worries regarding Dončić's athleticism, stating that "for a 19-year-old, he's got a really unusual combination of size, speed, and deceptive quickness." By his second year, Luka's ability to accelerate off a pick and blow by defenders to get to the basket is seen as one of his strengths. Given the false characterisation of his abilities and his subsequent success in the NBA, some speculate that prejudiced stereotyping might have had a role in his negative pre-draft evaluation.
Before his draft, basketball journalist and scout Austin Green compared Dončić to NBA players Paul Pierce and Joe Johnson. Dončić compared himself to Ben Simmons due to his versatility. In his second season, LA Clippers coach Doc Rivers, when asked about Dončić, stated that "there's a lot of people in him." He likened Dončić’s stepback 3-pointers to James Harden, his passing ability to Larry Bird, and his court vision to LeBron James. NBA analyst, Kendrick Perkins, called him "baby LeBron" due to his overall skill and dominance on the court.
