Giles Collier (1622–1678), was an English divine.
Collier was the son of Giles Collier of Pershore, Worcestershire, in which county he was born in 1622. In Lent term 1637 he became either a battler or a servitor at New Inn Hall, Oxford, taking the degrees of B.A. and M.A. in 1641 and 1648 respectively. When he left the university he became a presbyterian, subscribing in 1648 to the covenant, and was afterwards presented to the livings of Blockley and Evesham in Warwickshire.
In 1654 he was made assistant to the commissioners acting within that county for the ejection of 'scandalous, ignorant, and insufficient ministers and schoolmasters,' but on the Restoration he retained his livings by complying with the Act of Uniformity, to the disappointment of the neighbouring loyalists, who disliked his meddlesome and somewhat vindictive nature. He died at Blockley in July 1678, and was buried there.
