# List of WNBA annual blocks leaders

In basketball, a blocked shot occurs when a defender deflects or stops a field goal attempt without committing a foul. The Women's National Basketball Association's (WNBA) block title is awarded to the player with the highest blocks per game average in a given season. To qualify for the blocks title, the player must appear in at least 70 percent of the season's games (28games in typical 40-game season) or record 35 blocks.
Brittney Griner holds the all-time records for total blocks (129) and blocks per game (4.04) in a season; achieved in the 2014 season and 2015 season respectively. Griner and Margo Dydek have won the most block titles, with eight. Lisa Leslie, Sylvia Fowles, Candace Parker, and A'ja Wilson have also won the title more than once. Griner has also won the most consecutive block titles, with seven.
