William Territt Greswell (15 October 1889 – 12 February 1971) was an English first-class cricketer who played for Somerset from 1908 to 1930. But his career as a tea-planter with the family company in Ceylon meant that he appeared in only 115 first-class matches for the county in that period, and was a regular player in only five seasons, dotted over almost 20 years.
