Dr. Regan Shaw is a recurring character on NBC series Frasier. She is portrayed by Gigi Rice.
Regan is Frasier's neighbor, who Martin allowed to use their shower in order to keep her around. Frasier then took her to a ball. However, Regan thought Frasier focused too much on his brother's date, Poppy. She later appeared when she ran into Frasier in the episode "To Thine Own Self Be True".
