Ginger Grant is a fictional character portrayed by Tina Louise in the 1964 to 1967 television sitcom Gilligan's Island.

Louise also said that she was very grateful to the show's fans for their continued support over the years especially during the COVID-19 pandemic, "We brought a lot of joy to people and still do.
