The following are the seeded players. Seedings are based on WTA rankings as of 24 April 2023. Rankings and points before are as of 8 May 2023. Because the women's tournament is being expanded to two weeks this year, players are defending points from the
2022 Italian Open, as well as tournaments that took place during the week of 16 May 2022 (
Rabat and
Strasbourg). Points from the 2022 Italian Open are listed first in the "Points defending" column. The event is not mandatory on the women's side and points from the
2022 Italian Open are included in the table below only if they counted towards the player's ranking as of 8 May 2023. For other players, the points defending column shows the lower of (a) points from the player's second-highest non-mandatory WTA 1000 tournament (which are required to be counted in her ranking) or (b) her 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. }
