LeBron James and Giannis Antetokounmpo will return as NBA All-Star team captains after leading the vote for February's showpiece contest in Chicago.

Three newcomers – Luka Doncic, Trae Young and Pascal Siakam – will also take the floor for the 69th edition of the annual exhibition game.

Los Angeles Lakers superstar James captained Team LeBron to victory over Team Giannis in 2019 and the pair will renew their rivalry at United Center on February 16.

James, an All-Star for the 16th year of his illustrious career, will have the chance to draft Dallas Mavericks sensation Doncic onto his team for the first time, the MVP contender a walk-up selection amid a brilliant sophomore season in the NBA.

All-Star regulars James Harden, Anthony Davis and Kawhi Leonard round out the Western Conference starter pool.

Atlanta Hawks guard Young topped the count among Eastern Conference backcourt options to secure a start alongside the Boston Celtics' Kemba Walker.

The pair gained selection ahead of four-time All Star Jimmy Butler and the Philadelphia 76ers' Ben Simmons, who scored poorly in the fan portion of the vote.

Siakam's selection comes after averaging a career-best 23.5 points per game for the Toronto Raptors this season, while injury troubles failed to prevent Joel Embiid from sealing a frontcourt berth.

Fan ballots were weighted at 50 per cent, while current players and the media contributed 25 per cent of the starter vote.

Captains James and Antetokounmpo will select their teams from the eight other starters, while NBA head coaches will be responsible for choosing the 14 reserves that will be announced on January 30.

Eastern Conference starters:

Trae Young (Atlanta Hawks), Kemba Walker (Boston Celtics), Pascal Siakam (Toronto Raptors), Giannis Antetokounmpo (Milwaukee Bucks), Joel Embiid (Philadelphia 76ers)

Western Conference starters:

James Harden (Houston Rockets), Luka Doncic (Dallas Mavericks), Kawhi Leonard (Los Angeles Clippers), LeBron James (Los Angeles Lakers), Anthony Davis (Los Angeles Lakers)
