Rainald Knightley, 1st Baron Knightley (22 October 1819 – 19 December 1895), known as Sir Rainald Knightley, 3rd Baronet, from 1864 to 1892, was a British Conservative Party politician.

Knightley was the son of Sir Charles Knightley, 2nd Baronet of Fawsley, and his wife Selina Mary, daughter of F. L. Hervey. In 1864 he inherited the baronetcy and the Fawsley estate on the death of his father.

Knightley entered Parliament for Northamptonshire South in 1852 (succeeding his father), a seat he held until 1892. In 1892 he was raised to the peerage as Baron Knightley, of Fawsley in the County of Northampton.

Lord Knightley married Louisa Mary, daughter of General Sir Edward Bowater, in 1869. The marriage was childless. He died in December 1895, aged 76, when the barony became extinct. He was succeeded in the baronetcy by his first cousin Valentine Knightley. Lady Knightley died in October 1913.
