Madeley Old Manor was a medieval manor house at Madeley, Staffordshire. It is now a ruin, with only fragments of its walls remaining. The remnants have Grade II listed building status and the site is a Scheduled Ancient Monument. The Tudor manor house is illustrated by Michael Burghers as it appeared in 1686 in Plot's History of Staffordshire, together with the formal gardens and a later east frontage.
The manor, which had previously been leased to Sir Francis Poyntz, was sold in 1547 by Sir Edward Bray and Dame Joan, daughter and heiress of Sir Matthew Browne, to Thomas Offley (d. 1582), Merchant Taylor, who married Joan Nichols, and became Lord Mayor of London in 1556. Five generations of Offleys lived at the manor including three John Offleys who served as High Sheriff of Staffordshire. Sir Thomas Offley's son, Henry, married Mary, the daughter of Sir John White (of Aldershot), Lord Mayor of London (1563-64). Henry Offley's son and heir was Sir John Offley, who married Anne, daughter of Nicholas Fuller M.P., and several of their children married into notable families: William married Frances, daughter of John Lane of Bentley; Elizabeth married Sir Robert Jenney, son of Sir Arthur Jenney of Knodishall, Suffolk; and Katherine married first Thomas, son of Thomas Willis, and secondly his cousin William Willis.
Thomas Offley's great-great-grandson John Offley (b. 1649) married Anne Crewe, heiress of Crewe Hall, Cheshire. Their son, John Offley, changed his name by a 1708 Act of Parliament to John Offley Crewe when he inherited his mother's estate. Their grandson John Crewe (1742–1829) later became 1st Baron Crewe.
Madeley Manor was abandoned and fell into ruin following the building of the second Madeley Manor (O.S. Map Reference SJ 7759 4591).The family eventually made Crewe Hall their principal seat.
