The Gulf or Bay of Tolo (Indonesian: Teluk Tolo or Towori) is the body of water lying between the eastern and south-eastern peninsulas of the island of Sulawesi (Celebes) in Indonesia.
Unlike the Gulf of Tomini to its north or the Gulf of Boni to its south-west, the Bay of Tolo is not recognized as a gulf by the International Hydrographic Organization. Instead, it is included in the area of the Molukka Sea.
