Lord Henry Cavendish-Bentinck (28 May 1863 – 6 October 1931), known as Henry Cavendish-Bentinck until 1880, was a British Conservative politician.
Cavendish-Bentinck was the eldest son of Lieutenant-General Arthur Cavendish-Bentinck from his second marriage to Augusta Mary Elizabeth, 1st Baroness Bolsover. His paternal grandfather Lord William Charles Augustus Cavendish-Bentinck was the third son of William Cavendish-Bentinck, 3rd Duke of Portland, while William Cavendish-Bentinck, 6th Duke of Portland, was his half-brother. In 1880 he was granted the rank of a younger son of a duke on his half-brother's succession to the dukedom. He entered Parliament for Norfolk North-West in 1886, defeating Joseph Arch, a seat he lost in 1892, when Arch reclaimed the seat. He returned to the House of Commons in 1895 when he was elected for Nottingham South, a seat he held until 1906 and again from 1910 to 1929.
Cavendish-Bentinck married Lady Olivia Caroline Amelia, daughter of Thomas Taylour, in 1892. He died in October 1931, aged 68. Lady Olivia Caroline Amelia died in November 1939, aged 70.
