John Ker (died 1741) was a Scottish schoolteacher and academic, a classical scholar known as a Neo-Latin poet.
In 1717, he was appointed professor of Greek in King's College, Aberdeen, the first specialist teacher of the subject there, despite his admiration for the uncompromising Jacobite Archibald Pitcairne.
[1] On 2 October 1734, Ker succeeded Adam Watt in the Latin chair at Edinburgh University.
He studied law, and was a popular teacher, if (in the view of Alexander Carlyle) deferential to students from the nobility.
[1] About 1725, Ker published his Latin poem Donaides (those of the River Don), celebrating worthies of Aberdeen.
