Morrison's Haven is a harbour at Prestongrange, East Lothian, Scotland, UK, on the B1348, close to Levenhall Links, Prestongrange Industrial Heritage Museum, Prestonpans, and Prestongrange House. The name comes from the Morisons of Prestongrange. A part of Prestongrange were purchased by John Morison from the Kerr family in 1609. He was a burgess of Edinburgh, a bailie (1581) and treasurer of Edinburgh (1588). His son Sir Alexander Morison, a Lord of Session, developed the harbour. The property was purchased in 1746 from William Morrison by William Grant.
