2021 Connecticut Sun season

The 2021 WNBA season was the 23rd season for the Connecticut Sun franchise of the Women's National Basketball Association. It was also the 19th season for the franchise in Connecticut. The season began on May 14, 2021, at the Atlanta Dream.^[1]

The Sun started the season strongly and went on a five-game winning streak before losing their first game. They lost two of their last three games in May to finish with a strong 6–2 record in that month. The month of June was streaky for the Sun, with a three-game losing streak book-ended by a two-game winning streak and a three-game winning streak. Those streaks left the team with a 5–3 record in June. The Sun went 3–1 in July, the last month before the Olympic break. The team headed into the Olympic break with a 14–6 overall record.

The first game back from the Olympic break was the inaugural WNBA Commissioner's Cup, where the Sun faced off against the Seattle Storm in Phoenix. The game was difficult for the Sun and they lost 57–79. However, this result would not portend the rest of the team's results after the Olympic break. The Sun won their remaining seven games in August to finish the month with a 7–0 regular season record. Their dominance continued into September where the Sun went 5–0, to finish the season on a thirteen-game winning streak. Their final regular season record was 26–6, which earned them the top seed in the 2021 WNBA Playoffs. Their 26 wins was tied for the most regular season wins in franchise history with 2005 and 2006.

As the first seed in the playoffs, the Sun earned a double bye into the Semifinals and would have home-court advantage against the lowest remaining seed from the second round. After the second round, it was determined that the Sun would play the Chicago Sky. The series started off with a thrilling double overtime game that the Sun dropped 95–101. The Sun won the next game 79–68 to take a 1–1 series into Chicago. Chicago used their home court to their advantage and won the next two games and the series 3–1.
