She will play Carla, a compassionate woman who took Nikita (Maggie Q) in before she joined Division. The pair will reunite in the 14th episode of Nikita's second season, titled 'Rogue'.
Gimpel appeared as Coco Hernandez on NBC's Fame from 1982 to 1987 and has since played major roles on ER, Veronica Mars and Boston Legal.
Late last year, Nikita star Dillon Casey was promoted to a series regular, having debuted as Division operative Sean Pierce in the show's second season premiere.
