The biggest stage of the NBA regular season is almost upon us!

NBA Christmas Day is always packed with good matchups and intreguing storylines and this year's slate is no different.

Take a look at which teams go head-to-head on this marquee day.

All times are Eastern.

Who plays on NBA Christmas Day?

12 p.m. – Boston Celtics at Toronto Raptors

This is the second of four meetings between the Atlantic Division foes. Boston took care of business at home way back at the start of the season on Oct. 25, defeating the Raptors112-106.

The Celtics haven't beaten the Raptors in Toronto since 2015, as the Raptors have won seven-consecutive games against Boston at Scotiabank Arena.

2:30 p.m. – Milwaukee Bucks at Philadelphia 76ers

This is a heavyweight battle between two of the best teams in the Eastern Conference. The Bucks and 76ers have yet to face off this season, saving the first highly anticipated matchup for Christmas Day. The last time these teams faced off last season, it was a back-and-forth slugfest between Joel Embiid and Giannis Antetokounmpo as The Greek Freak's 45 points edged Embiid's 34-point, 13-rebound, 13-assist triple-double.

5:00 p.m. – Houston Rockets at Golden State Warriors

While this matchup lost a bit of its luster with the injury to Stephen Curry derailing the Warriors' season, there's still another reason to tune in to this game. James Harden has been as unstoppable as we've ever seen him as a scorer and Golden State owns a bottom-five defence in the league in terms of defensive rating . Will Harden put on a historic scoring performance on Christmas Day?

8:00 p.m. – LA Clippers at Los Angeles Lakers

The Clippers defeated the Lakers on opening night without Paul George and everybody was ready to crown them as the NBA Champions of the 2019-20 season. Since then, the Lakers have rolled their way to one of the best records in the league and have shown no signs of slowing down. This battle for the STAPLES Center will be the highlight of Christmas Day with both teams at full strength.

10:30 p.m. – New Orleans Pelicans at Denver Nuggets

This matchup loses some of its juice with Zion Williamson's absence due to the knee injury that has kept him sidelined before the start of his rookie season. This is still a good opportunity to catch the Denver Nuggets – one of the best teams in the Western Conference – go head-to-head with the potential Most Improved Player of the Year in Brandon Ingram.
