Name derived from Lathlain Park Oval which was in turn named after Sir William Lathlain. The proposal for the renaming of parts of the localities of Victoria Park and Rivervale as Lathlain was suggested by the City of Perth, and was approved in 1981. Sir William Lathlain was Mayor of Perth 1918-23 and 1930-32, and also a member of the Legislative Council 1926-32.

Former Western Australian Premier Dr Geoff Gallop produced a series called Know your Suburb during his time as a Member for Victoria Park. Read the Lathlain publication online or ask for a hardcopy at the Library front counter.
