Baron Cawley, of Prestwich in the County Palatine of Lancaster, is a title in the Peerage of the United Kingdom. It was created in 1918 for the Liberal politician Sir Frederick Cawley, 1st Baronet. He had previously represented Prestwich in the House of Commons and served as Chancellor of the Duchy of Lancaster from 1916 to 1918. Before his elevation to the peerage, Cawley had been created a baronet, of Prestwich in the County Palatine of Lancaster, in the Baronetage of the United Kingdom, in 1906. His grandson, the third Baron, notably served as Deputy Chairman of Committees in the House of Lords from 1958 to 1967. As of 2011[update] the titles are held by the latter's eldest son, the fourth Baron, who succeeded in 2001.
The Honourable Harold Thomas Cawley, second son of the first Baron, the Honourable Stephen Robert Cawley, second son of the second Baron, and the Honourable Oswald Cawley, fourth son of the first Baron, were all Liberal politicians.
The former seat of the Cawley family was Berrington Hall near Leominster in Herefordshire.
The heir apparent is the present holder's son Hon. William Robert Harold Cawley (b. 1981).
