The Rockingham Whigs (or Rockinghamites) in 18th century British politics were a faction of the Whigs led by Charles Watson-Wentworth, 2nd Marquess of Rockingham from about 1762 until his death in 1782. The Rockingham Whigs briefly held power from 1765 to 1766 and again in 1782, and otherwise were usually in opposition to the various ministries of the period.
