Kathleen Gill Atkinson (November 5, 1875 – April 30, 1957) was an American tennis player.
With her older sister, Juliette, both residents of Maplewood, she won the US Women's National Championship in women's doubles 1897 and 1898. They were the first sisters to win a title together and the first to play each other in a semi final until the Williams sisters played in the final.
