Plasterfield (Scottish Gaelic: Raon na Crèadha) is a hamlet in the Scottish Outer Hebrides, on the Isle of Lewis. Plasterfield is within the parish of Stornoway.

Plasterfield is a suburb of Stornoway and consists of two groups of houses, built after World War II. The ambulance station for the Isle of Lewis is also here as well a small industrial estate (Mossend estate). In the 1970s a group of Barratt houses was built adjacent to Plasterfield; this area was originally called Bayview. Plasterfield is also the home of The Blackhouse bakery (formerly MacKinnon's).

Angus Macleod, the former Scottish editor of The Times, was raised in Plasterfield.
