Peter Rollock or Rollo of Pilton (c. 1558–1632) was a Scottish judge and Bishop of the Church of Scotland.
The sixth and youngest son of Andrew Rollock, laird of Duncrub, Perthshire, and his wife, Marion Rollo, heiress of David Rollo of Menmuir, he became a Law student at St Mary's College, St Andrews qualifying as an advocate in 1573 and further gaining a Master of Arts degree in 1575.
Rollock experienced a fluctuating position in the higher echelons of government, losing (1609) and regaining (1610) and then resigning (1620) his place on the bench, and going in (1587) and out (1610) and in again (1616) and then leaving (1625) the Privy Council.
On 21 September 1611 an attempt was made on his life by two sons of Matthew Finlayson of Killeith or Kinleith, with whom he was in the midst of a lawsuit.
He then married (1607) Elizabeth Weston, widow of John Fairlie of Bruntsfield and had one son, Walter Rollock.
