William Mackworth

William Augustus Mackworth (3 March 1825 – 4 December 1855) was a Trinidad-born English cricketer who played one first-class cricket match for Cambridge University in 1845 and another for Manchester in 1848. He was born in Trinidad where his father was high sheriff and died at St Kilda, Melbourne, Australia.

Mackworth matriculated at Trinity College, Cambridge in 1844 but it is not recorded if he took a degree. His death at the end of 1855 came "after an illness of ten days".

As a cricketer, Mackworth was a middle-order batsman; there is no record that he bowled nor is it known whether he was right- or left-handed. He appeared for Manchester in minor matches in both 1847 and 1848.
