The Egerton, later Grey Egerton, later still Egerton baronetcy, of Egerton and Oulton in the county of Chester, is a title in the Baronetage of England held by the senior patrilineal branch of the Egerton family.
One of the earliest English baronetcies created, Sir Roland Egerton left many male descendants in remainder to his title.
The baronetcy was created on 5 April 1617 for Sir Roland Egerton, whose family were established by the 13th-century in Cheshire. The Anglo-Norman chevalier David le Clerc de Malpas migrated to England, and was appointed justice for Cheshire by King Henry III in 1252. Le Clerc held three knights' fees for the county, owing the King their service as and when summoned to war. His second son named Philip le Goch (translated from the brythonic as 'the Red') was lord of the manor of Egerton, Cheshire.
The late 15th-century head of the family, Philip Egerton of Egerton, married Margery, daughter of Sir William Mainwaring; he died in 1474 at the height of the civil strife, leaving a number of sons: the second was Sir Ralph Egerton of Ridley, whose illegitimate son by a concubine, Alice Sparks, was Thomas Egerton, created Viscount Brackley after rising to high office in the Elizabethan court (see Earls and Dukes of Bridgewater). Their elder son, John Egerton of Egerton (died 1483), married Elizabeth, daughter and heir of Hugh Done of Oulton, and paternal granddaughter of James Touchet, Lord Audley. Their only son was Philip Egerton of Egerton and Oulton (died 1534), who married Joan, a widow of Sir Richard Winnington and daughter and coheir of Gilbert Smith of Cuerdley, Lancashire, leaving only one son: Sir Philip (died 1563) who married Eleanor, daughter of Sir Randle Brereton, of Malpas; their eldest son was John Egerton (died 1590) married Jane, daughter of Sir Piers Mostyn, whose eldest son was Sir John Egerton.
