Ada Winifred Weekes Baker (11 December 1866 – 24 July 1949), known professionally as Madame Ada Baker, was an Australian soprano, vaudeville star and singing teacher. Born in Strawberry Hills, Sydney, she moved with her family to Wagga Wagga where she taught singing. Upon returning to Sydney she received further training under Albert Fisher. She debuted to much acclaim at the Promenade Concerts in 1886 at Surry Hills. She married Charles Hall, a law clerk, in 1887 and had two children. The couple filed for divorce in 1897, which was not granted, but they had already separated.
