Pinterest doesn't have a built-in feature to directly restore a deleted board. However, you can check the "Recently Deleted" section on your profile to see if your board is still restorable. If it's listed there, click on it and choose the "Restore" option at the top of the board to bring it back. Keep in mind that Pinterest may not retain recently deleted boards for an extended period, so it's essential to check as soon as possible if you want to recover a deleted board.
