The B-class Melbourne tram is a class of two-section, three-bogie articulated class trams that operate on the Melbourne tram network. Following the introduction of two B1-class prototype trams in 1984 and 1985, a total of 130 B2-class trams were built by Comeng (later ABB), Dandenong.

They were developed for the conversion of the St Kilda and Port Melbourne railway lines to light rail, and introduced by the Metropolitan Transit Authority, and later the Public Transport Corporation between 1984 and 1994.
