Easton Dudley Ashley St John McMorris (4 April 1935 – 1 February 2022) was a West Indian cricketer who played in 13 Tests from 1958 to 1966. He attended Kingston College. An opening batsman, McMorris scored a Test century against India at his home ground of Sabina Park in the 1961-62 series, adding 255 for the second wicket with Rohan Kanhai. This series was his most productive: in the four matches he played he scored 349 runs at an average of 58.16, with a lowest score of 37. He toured England with the West Indies team in 1963 and 1966 but was less successful on the slower, greener pitches. He scored 190 not out against Middlesex in 1963, but it took 400 minutes.
