The 2021 WNBA season was the 14th season for the Atlanta Dream of the Women's National Basketball Association. The team began the season on May 14, 2021 at home against the Connecticut Sun.
This was the first season that the Dream will play home games at the Gateway Center Arena at College Park. In the 2019 offseason the team elected to move from State Farm Arena. However, due to the COVID-19 pandemic, the 2020 season was played at a neutral site.

Mike Petersen began the season as interim head coach, but stepped down on July 24 due to health reasons. Darius Taylor took over as interim coach through the end of the regular season.

The Dream began the season by losing their first two games, but then going on a four game winning streak. That win streak was followed by a four game losing streak. After winning their next game, the Dream were 5–6 through their first eleven games. However, the Dream could only win one more of their next eight games to go into the Olympic break with a record of 6–13. The team's struggles continued after the break as they lost seven straight games. They did manage to win two of their last five games to finish with an 8–24 record.
