Christopher Edwin Theakstone (born 10 March 1812; date of death unknown) was an English first-class cricketer. While chief cashier of the Portsmouth branch of the Bank of England in March 1861 he absconded with over £1000. During his arrest the following month in Lambeth he cut his throat with a razor but survived. He was charged with embezzlement, pleaded guilty, and was sentenced to four years imprisonment. He was born in Pentonville, London.
Theakstone represented Hampshire, making his first-class debut in 1848 against an All-England Eleven. Theakstone played one further match for the county against the same opposition in 1849.
