Bentinck was the eldest son of Captain John Albert Bentinck, of Terrington St Clement, Norfolk, and his wife Renira van Tuyll van Serooskerken.
He followed his father into the British Royal Navy. He served at the latter end of the American War of Independence, commanding the 'Assistance' in 1783, at the age of 19. His logbook records subsequent journeys in North America in 1784.
Bentinck commanded the 'Adamant' in 1793-1794 during the War of the First Coalition, and the 'Phaeton' during the Battle of the Glorious First of June in 1794. From July 1794 to March 1795 he commanded the 'Tremendous'.
Between 1798 and 1802 Bentinck served as Governor of St Vincent and the Grenadines.
In 1800, his grandmother Charlotte Sophie, Countess Bentinck, died, and bequeathed him an estate at Doorwerth in The Netherlands.
By 1805 Bentinck was living on his estate in Norfolk, and commanding the Sea Fencibles, a coastal defence force against the French. He was promoted to Rear-Admiral of the
Blue in 1805, Rear-Admiral of the White in 1808, and Vice-Admiral of the
Blue in 1810. He died of typhus in St Petersburg on 21 February 1813.
