Petrus Johannes (Pieter) van Bleeck (baptized 25 June 1697, The Hague – 20 July 1764, London) was a Dutch portrait painter and engraver active in London, where he moved in 1723.
Van Bleeck is especially known for theatrical subjects such as Owen Swiny, Kitty Clive and Margaret Woffington, but he also worked on other subjects such as James Foster. His paintings were frequently engraved, particularly by John Faber Junior. He was the son of Richard van Bleeck.
