Baron Northwick, of Northwick Park in the County of Worcester, was a title in the Peerage of Great Britain. It was created in 1797 for Sir John Rushout, 5th Baronet, for many years Member of Parliament for Evesham. He was succeeded by his son, the second Baron, who was a noted collector of art. He, in turn, was succeeded by his nephew, the third Baron, the son of George Rushout-Bowles (who had assumed by Royal licence the additional surname of Bowles in 1817, which was that of his maternal grandfather Humphrey Bowles), younger son of the first Baron. He represented Evesham and Worcestershire East in Parliament. Lord Northwick had no surviving children and the titles became extinct on his death in 1887.
