Joachim Ledesma was a male Human who lived in the 24th century. In the 2370s, Ledesma held the rank of Admiral in Starfleet and was Benjamin Sisko's overall commander.

In 2370, Admiral Ledesma and Vice Admiral Estellan Angerich spoke to Sisko on the matter of the Helios. After Elim Garak gave Julian Bashir information on the Helios, Ledesma was concerned that Garak was trying to distract Starfleet from the Cardassian fleet movements along the border. Ledesma gave Sisko orders to capture the Helios and bring her crew to trial in the Federation. (DS9 novel: Proud Helios)
