The following are the seeded players. Seedings are based on WTA rankings as of 7 August 2023. Rank and points before are as of 14 August 2023.

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.
† Points from the player's 16th best result (for points defending) or 17th best result (for points earned), in each case as of 14 August 2023.
‡ Points from the player's second-best non-mandatory WTA 1000 event, which are required to be counted in her ranking.
