Sir Richard Percy (died 1648) was an English soldier who served in Ireland during the 1590s.
Following the outbreak of Tyrone's Rebellion in Ireland, he raised a regiment, of which the majority were drawn from Wales, to supplement the under-strength Irish Army. The regiment was badly mauled during the Battle of the Yellow Ford in 1598 when, as the advance guard of the relief expedition to a besieged fort on the River Blackwater, they were attacked by Hugh O'Neill, Earl of Tyrone's rebel forces. Percy's regiment suffered heavy losses in what amounted to a major defeat in which the Marshal of Ireland, Sir Henry Bagenal, was killed.
