Francis Lascelles (1612-1667), also spelt Lassels, was an English politician, soldier and businessman who fought for Parliament in the 1639-1652 Wars of the Three Kingdoms and was a Member of Parliament between 1645 and 1660.
Although nominated to the Commission that tried Charles I in 1649, he did not sign the death warrant and largely escaped punishment after the 1660 Restoration, although he was fined and barred from holding public office.
