William Wishart (or Wischard) (died 28 May 1279) was a 13th-century Bishop of St. Andrews. He was postulated to the see of St. Andrews (Cell Rígmonaid or Cill Rìmhinn) while holding the position as Bishop-elect of Glasgow, which he resigned when, on 2 June 1271, he was elected to that vacant see. He was succeeded at Glasgow by his cousin (consanguieus), Robert Wishart. His election to St. Andrews was notable, because apparently the bishopric's Céli Dé community were excluded from the election. Pope Gregory X charged the Bishop of Moray, the Bishop of Aberdeen, and the Bishop of Argyll, to look over the character of the elect and to investigate the legitimacy of the election, of the latter of which the Pope had suspicions. William, however, emerged successfully, and was consecrated at Scone on 15 October 1273.
