Christmas Day and Christmas Eve games in the National Football League (NFL) are an occasional part of the league's schedule. In contrast to Thanksgiving Day games, however, they are not an annual occurrence; as of 2020, there have been just 22 Christmas Day games in the NFL's history.

After the NFL held two Divisional Playoff games on Christmas Day in 1971, the league avoided any more games on Christmas Day until 1989. Since then, the NFL has held occasional games on Christmas Day in some years, as part of week 16 or 17 of the regular season. Two games were played each Christmas Day from 2004 to 2006 and then from 2016 to 2017.
