Sir Michael Livesey, 1st Baronet (1614 - circa 1665), also spelt Livesay, was a Puritan activist and Member of Parliament who served in the Parliamentarian army during the Wars of the Three Kingdoms.

At the outbreak of the First English Civil War in August 1642, Livesey played a prominent role in securing Kent for Parliament, raising a regiment of cavalry and serving on the local administration.

[6] Known as a devout Puritan [a] his marriage connected him to Theophilus Clinton, 4th Earl of Lincoln and William Fiennes, 1st Viscount Saye and Sele, both leading opponents of Charles I.

[8] In February 1642, he organised and presented a petition to the Long Parliament on behalf of 'the Knights, Gentry and Commonalty of the County of Kent', which expressed support for the reforms carried out since November 1640.

[11] He missed the Battle of Alton on 13 December preventing an attack on Bramber, which controlled the road into East Sussex and Kent, important for its wealth and access to ports in Northern Europe.

When pro-Royalist riots broke out in Kent in December 1647, Livesey was sent to quell them; he remained in South East England when the Second English Civil War began in April 1648, suppressing unrest in Sussex and supporting Sir Thomas Fairfax in the campaign which ended with the capture of Maidstone in June.

[17] On 4 July, a petition was presented to Parliament demanding the resumption of negotiations with Charles, and on the same day, the Earl of Holland raised 400 cavalry in an attempt to seize London.

[20] The Second Civil War was fought with greater bitterness than the first, with both sides executing prisoners, while it convinced Livesey, Oliver Cromwell and others that further talks with Charles were pointless.

He confined himself to local politics, serving as High Sheriff of Kent in 1655 and 1656 and when the Rump was reinstated in May 1659, he supported the civilian faction in Parliament against the Army's Wallingford House party.
