Frederick William Cumberland (10 April 1821 – 5 August 1881) was a Canadian engineer, architect and politician.

The family returned to London in the mid-1830s, where he studied at King's College School and apprenticed as a civil engineer.

Starting in 1843, he was employed with the engineering department of the British Admiralty, working on the construction of dry docks and fortifications.

[citation needed] In partnership with architect Thomas Ridout, he designed the Cathedral Church of St. James and School, the York County Court House, and a post office.

As was common at the time, he used railway money to gain the support of Members of Parliament and to help elect candidates favourable to their cause.
