Warwick Mohun, 2nd Baron Mohun of Okehampton (25 May 1620 – 1665) was an English politician who sat in the House of Commons in 1640 until he inherited his peerage and sat in the House of Lords.
On the outbreak of the English Civil War Mohun left Westminster and retired to his house in Cornwall.
He eventually took up arms for the Royalist cause in September 1642 and raised a regiment of foot in his own area in spite of his unpopularity there.
He was fined for delinquency although the disputes about the amount to be paid lasted a long time.
Mohun married Catherine Welles of Brember in Hampshire and had two sons and three daughters.
