Norton Powlett (1680–1741) of Rotherfield Park and Amport, Hampshire, was a British landowner and Whig politician.
At the 1705 English general election, he was returned as Member of Parliament for Petersfield on his own interest.
He was among those ordered in February 1707 to prepare a bill for a turnpike on the Petersfield to Butser Hill road.
He acted as teller again and on 21 February 1711 was added to the drafting committee for a turnpike bill for the Petersfield to Portsmouth road.
He voted for the motion of ‘No Peace without Spain’ and against the French commerce bill on 18 June 1713.
His eldest son, Norton, was MP for Winchester (UK Parliament constituency).
