Colonel John Birch (7 September 1615 – 10 May 1691) was an English soldier and politician, who fought for the Parliamentarian cause in the First English Civil War, and sat in the House of Commons at various times between 1646 and 1691. Excluded from Parliament in Pride's Purge of December 1648, he was also prevented from taking his seat for Leominster under the Protectorate. After the 1660 Restoration, he sat on over 122 Parliamentary Committees, particularly those connected with finance.
