Sir Henry Holcroft (1586–1650) was an English politician who sat in the House of Commons between 1624 and 1629 and held appointments in the Dublin Castle administration in Ireland.
[4] The influence of Holcroft's ally, George Villiers, 1st Duke of Buckingham, ensured that he retained the role after the accession of Charles I of England in 1625.
He was elected MP for Newton in 1628 and sat until 1629 when King Charles decided to rule without parliament for eleven years.
[2] After the assassination of Buckingham, Holcroft served as a member of a new committee for dealing with Irish petitions and grievances.
[2] In 1634, he retired from duties in London and Dublin and became a justice of the peace in Essex, where he owned land at Greenstreet House, East Ham.
