Kathleen Wenzel was a Human woman of the mid-22nd century. She held the rank of lieutenant in the Federation Starfleet.

On reference stardate 0/9101.13 (c. 2163), Wenzel visited Rigel IV and became the first representative of the new United Federation of Planets to meet the Rigellians on their homeworld. (FASA RPG module: The Orions: Book of Deep Knowledge)

A Federation ambassadorial delegation arrived on Rigel VIII at the same time, suggesting that Wenzel was attached to that, or that two delegations traveled together to the neighboring planets.
