The Great Grimsby Street Tramways Company was a tramway serving Grimsby and Cleethorpes in Lincolnshire, England. It was a subsidiary of the Provincial Tramway Company. The tramway opened in 1881 using horse-drawn trams on standard gauge track, stretching from the depot in Park Street, on the Grimsby/Cleethorpes boundary, to People's Park in Grimsby. In 1887 the route was extended to Kingsway in Cleethorpes. A branch departed the main line at Riby Square to serve Freeman Street. In 1901, electric trams replaced the horses. Six trailer cars were operated until 1918, mainly on football match days, in addition to 31 four-wheeled double-deck electric cars. An open touring car was built in 1922.
