Greville was the second son of Francis Greville, 1st Earl of Warwick, and his wife, Elizabeth Hamilton, daughter of Lord Archibald Hamilton. George Greville, 2nd Earl of Warwick, and Robert Fulke Greville were his brothers, and he had four sisters. He was brought up in the family home, Warwick Castle. His father had been created Earl Brooke three years before he was born and in 1759 had successfully petitioned to have the prestigious medieval title of a more senior extinct line of his family, Earl of Warwick, conferred on him as the senior male heir of the family and lieutenant of the county. He was educated at the University of Edinburgh from 1764 to 1767.

When his father died in 1773 and his brother became Earl of Warwick, Greville effectively inherited the latter's seat (one of two for the Borough of Warwick) in the unreformed House of Commons. He was appointed in 1774 and held the seat until 1790. He served as a Lord of the Treasury from 1780 to 1782, as Treasurer of the Household from 1783 to 1784 and as Vice-Chamberlain of the Household from 1794 to 1804 and was sworn of the Privy Council in 1783.

• Illustration — The Hakin Observatory The construction of the seaport of Milford Haven, Pembrokeshire, South Wales, is due to Greville's entrepreneurial spirit. When it was the property of Sir William Hamilton, Greville applied for an Act of Parliament to enable Hamilton and his heirs to make docks, construct quays, establish markets, with roads and avenues to the port, to regulate the police, and make the place a station for conveying the mails. The first structure was a coaching inn. Quaker whaling ship owners from Nantucket were induced to settle, and for some decades Milford was a whaling port. A royal dockyard was established during the Napoleonic Wars. At his death in 1803, Hamilton bequeathed it to his nephew. At a site on high ground in nearby Hakin, Greville planned to build the College of King George the Third to allow the study of mathematics and navigation, whose centrepiece would be an observatory. Although the observatory was built, and scientific instruments delivered, the college never functioned as such as after the death of Greville in 1809 the whole project was abandoned.

Greville never married, but had a liaison with Emma Hamilton for several years when she begged for his help after becoming pregnant with Sir Harry Fetherstonhaugh's child in 1782 and he rejected her. Greville took her in on condition that the child, Emma Carew, was fostered out, and Emma Hamilton became his mistress. He later helped to engineer her meeting and subsequent marriage to his uncle Sir William Hamilton, perhaps in an attempt to win his favour and also to clear the way for him (Greville) to finding a wealthy wife. He lived for years in a house he had built facing Paddington Green, then a village on the outskirts of London, not far from the house in which he had installed Emma and her mother. He kept Romney's paintings of Emma on the walls of his house until his death. There he indulged his passion for gardening in a large garden provided with glasshouses in which he grew many rare tropical plants, aided by his connection with Banks, and managed to coax Vanilla planifolia to flower for the first time under glass, in the winter of 1806–07. His contributions to the herbarium assembled by Sir James Edward Smith are preserved by the Linnean Society of London. The Australasian genus Grevillea is named in his honour. In the latter part of his life he lived at Warwick Castle. Greville died on 23 April 1809, aged 59.

Grevillea, a diverse genus of about 360 species of evergreen flowering plants in the family Proteaceae, is named after him, due to his role as a patron of botany and co-founder of the Royal Horticultural Society. Greville Island, in Australia, was named to honour his memory by Francis Barrallier, in 1820. Greville plays a role in Susan Sontag's 1992 novel The Volcano Lover, about Sir William Hamilton.

Recorded positions include Treasurer of the Household, Vice-Chamberlain of the Household, member of the 14th Parliament of Great Britain, member of the 15th Parliament of Great Britain and member of the 16th Parliament of Great Britain. He belonged to Royal Society.
