Baron Lilford, of Lilford in the County of Northampton,^[1] is a title in the Peerage of Great Britain. It was created in 1797 for Thomas Powys, who had previously represented Northamptonshire in the House of Commons. His grandson, the third Baron, served as a Lord-in-waiting (government whip) from 1837 to 1841 in the Whig administration of Lord Melbourne. He was succeeded by his son, the fourth Baron, an ornithologist.

On the death of his younger son, the sixth Baron (who succeeded his elder brother), in 1949, the line of the third Baron failed. The late Baron was succeeded by his second cousin twice removed, the seventh Baron. He was the great-great-grandson of Robert Vernon Powys, second son of the second Baron. As of 2010, the title is held by his only son Mark Powys, the eighth Baron, who succeeded in 2005. The family seat from 1711 until the 1990s was Lilford Hall in Northamptonshire.

The current Baron Lilford retains ownership of land in Jersey, South Africa and West Lancashire, including the Bank Hall Estate, which were inherited in 1860 by Thomas Atherton Powys, 3rd Baron Lilford, upon the death of his wife's cousin George Anthony Legh Keck.^[2]
