Leda was an Aldean artist in the 24th century. She was a member, along with Accolan, of unit B 375.
By 2364 Leda, along with many other Aldeans, was suffering from radiation poisoning as a result of the depletion of their planet's ozone layer and exposure to ultraviolet radiation from their sun. Luckily for Leda, her exposure had not become so severe that Aldean medicine could not treat the lesions and other symptoms she experienced.
Along with Accolan, she briefly supervised the training of Harry Bernard when he was on the planet and helped him to discover his natural talents as a sculptor. (TNG: "When The Bough Breaks")
Leda was played by Michèle Marsh.
