The following are the seeded players. Seedings are based on WTA rankings as of 31 July 2023. Rank and points before are as of 7 August 2023.

The event is not mandatory on the women's side and points from the 2022 tournament are included in the table below only if they counted towards the player's ranking as of 7 August 2023. For other players, the points defending column shows the player's 16th best result.

Points defending will be replaced at the end of the tournament by the highest of (a) the player's points from the 2023 tournament, (b) her 17th best result, or (c) points from her second-highest non-mandatory WTA 1000 event.
