John Fenwick Burgoyne Blackett (21 March 1821 – 25 April 1856) was a British politician.
Blackett was born at Manchester Square, Marylebone,[2] the oldest son of Christopher Blackett, a Member of Parliament (MP) for Northumberland South.
Blackett shortly after came to London, and studied for the bar, as well as contributing to the Edinburgh Review.
He was noted for his regular and punctual attendance to Parliament, but constant hard work wore him out and he retired in 1856, resigning his seat by appointment as Steward of the Manor of Northstead.
Blackett then moved to continental Europe to try to regain some energy, dying at Villeneuve-sur-Yonne, France.
