Cat Singh was a Human Starfleet officer who served as chief engineer aboard the USS Enterprise-C in the early 2330s.

She was Captain Rachel Garrett's closest friend and comrade aboard the Enterprise-C, and was noted by the crew as being the member of the command crew which was constantly on the move. (ST short story: "Hour of Fire")

Cat Singh should not be confused with the male officer Singh who served as chief engineer aboard the Enterprise-C at the time of its battle at Narendra III.
