Adam de Lanark, O.P. (died 1378) was a 14th-century Scottish Dominican friar and prelate. Possibly from a Lanark burgess family, he was a Dominican and a priest by 1356, and by 1364 was styled Magister, indicating the completion of a long university education. He first appears in the sources, c. 1355/6 as a confessor of King David II of Scotland; he retained this royal position through the 1350s and into the 1360s; Adam received a number of English safe-conducts (between May 1356 and August 1357) to visit King David, who for a time was a prisoner in England.
