The lake was renamed Lake Victoria after Queen Victoria by the explorer John Hanning Speke, in his reports- the first Briton to document it. (It has since been recognized that the native guides used the name Lake Nyanza to describe it to him) Speke accomplished this in 1858, while on an expedition with Richard Francis Burton to locate the source of the Nile River. This expedition was financially sponsored by the Royal Geographic Society, an imperial organization that upon bestowing this news to the queen, got bestowed a royal charter. It is not clear if this was in appreciation of the lake re-naming
