William Meldrum (died 1514 × 1516) was a prelate in the late 15th- and early 16th-century kingdom of Scotland.
He appears to have come from the Meldrum family of Seggie, as suggested by the otters on his arms.
[2] His appointment had been foreseen before the death of his predecessor John Balfour; by 4 June 1488 Meldrum had been selected to succeed to the bishopric upon the expected "resignation or death of the reverend father in Christ, John Balfour, now bishop of Brechin".
[2] He was consecrated sometime between 30 January (described as "elect") and 7 July (described as "bishop") 1489.
[2] Bishop Meldrum is recorded for the last time in possession of the see on 8 December 1514, and is dead by 19 March 1516, dying at some stage between.
