Sir Robert Baynard (1563–1636) was an English barrister and member of parliament.
He was the eldest son of Edward Baynard of Lackham, Wilshire, educated at Clare College, Cambridge (1580) and trained in the law at the Middle Temple (1581).
He was elected a Member (MP) of the Parliament of England for Chippenham in 1584 and Westbury in 1586.
After his death, a series of brass plaques were placed in the floor of St Cyriac's Church in Lacock, commemorating his life.
These were stolen in mid-2004, but quickly returned after a national appeal by police.
