Yoko Tani (谷洋子, Tani Yōko, 2 August 1928 – 19 April 1999) was a French-born Japanese actress and nightclub entertainer.

Tani was born in Paris. Her birth name was Itani Yōko (猪谷洋子). She has occasionally been described as 'Eurasian', 'half French', 'half Japanese' and even, in one source, 'Italian Japanese', all of which are incorrect.
