James Gadderar (1655–1733) was a clergyman of the Scottish Episcopal Church. Previously a minister at Kilmaurs, he was consecrated a college bishop on 24 February 1712 by Bishop George Hickes (i.e. a bishop without a diocese.) In November 1721 he traveled to Aberdeen and acted as Bishop Archibald Campbell's vicar-depute. Gadderar supported the practice of primitive 'usages' in the diocese, which brought him into a dispute with the College of Bishops at Edinburgh. After the resignation of Bishop Archibald Campbell in 1725, he was made Bishop of Aberdeen, remaining there until his death.
