W.S. Leslie (fl. 1870's) was a British Christy's style singer and performer.

He was apparently attached to the St James Hall, London and may have been the same Mr Leslie who first appeared in Cape Town with Charles Fraser in three pieces during 1858, playing the lead in A Blighted Being (Taylor). (see Charles Fraser).

He is most probably one of the three the co-founders of the Christy's troupe known as the Steele-Leslie-Taylor's Christy's Minstrels active in Cape Town and Port Elizabeth in 1865 and certainly a member of the touring Harvey-Dougherty-Leslie-Braham Minstrels, that visited the Cape Colony for a set of three seasons, between November 1872 and the end of 1874.
