Mithra de Silva Wettimuny (11 June 1951 – 20 January 2019) was a Sri Lankan cricketer who played in two Test matches and one One Day International (ODI) in 1983.

His elder brother Sunil played in the 1975 and 1979 Cricket World Cups while his youngest brother Sidath scored Sri Lanka's first Test match hundred.

Wettimuny originally came to prominence as captain of the successful Ceylon Schools team which toured India in 1969/70, a team which included future Test captains Bandula Warnapura and Duleep Mendis.

Sri Lanka gained Test status in 1982, and by then in his early thirties, Wettimuny's entire first-class cricket career incorporated nine matches in four countries in 127 days.
