Hector Boece (/ˈbɔɪs/; also spelled Boyce or Boise; 1465–1536), known in Latin as Hector Boecius or Boethius, was a Scottish philosopher and historian, and the first Principal of King's College in Aberdeen, a predecessor of the University of Aberdeen.

He was born in Dundee where he attended school and was educated at the nearby University of St Andrews. Later he left to study at the University of Paris where he met Erasmus, with whom he became close friends while they were both students at the austere Collège de Montaigu, to whose reforming Master, Jan Standonck, Boece later became Secretary. By 1497 he had become a professor of philosophy at Collège de Montaigu.

In 1500, he was induced to leave Paris for Aberdeen by a generously financed offer to become the first principal of the newly established University of Aberdeen, created at the behest of James IV by William Elphinstone, Bishop of Aberdeen under the authority of a Papal bull issued by Pope Alexander VI.

From then onwards, he worked closely with Elphinstone, to set up the new university and by 1505, regular lectures were taking place at King's College. The university structure was modelled on those of Paris and of Orléans. As intended, Boece was installed as the first principal of the university and gave lectures on medicine and on divinity.

At the end of 1534, Boece became Rector of Fyvie. He died in Aberdeen two years later at the age of 71.

Boece wrote and published two books, one of biography and one of history. In 1522 he published the Vitae Episcoporum Murthlacensium et Aberdonensium (Lives of the Bishops of Murthlack and Aberdeen) and in 1527 the Historia Gentis Scotorum (History of the Scottish People) to the accession of James III of Scotland. The former was the basis of a poem in Scots by Alexander Gardyne.

The Historia is the work for which Boece is remembered, as the second scholarly history of the Scots to be written; its only real predecessor was the compendium of John Mair. It was written in a flowing and pleasing style, became popular, and led to ecclesiastical preferment and royal favour. By modern standards, it is overly patriotic, and has many inaccuracies. The historical account of Macbeth of Scotland, in particular, flattered the antecedents of Boece's patron King James IV of Scotland, and greatly maligned the real Macbeth. The work was well received at the time, both in Europe and in Scotland, after its translation from Latin into French and then in 1536 from Latin into Scots by John Bellenden. There are some interesting glimpses in the Historia of contemporary Scotland, such as the statement that the Eurasian beaver, which was soon to become extinct in Scotland, was still common around Loch Ness.

Boece's Historia as published terminated its coverage of history at the year 1438. In the early 1530s the scholar Giovanni Ferrerio, engaged by Robert Reid of Kinloss Abbey, wrote a continuation of Boece's history, extending it another 50 years, to the end of the reign of James III. John Lesley in his De Origine, Moribus, et Rebus Gestis Scotorum, and Robert Lindsay of Pitscottie, provided further continuations. The metrical translation into Scots by William Stewart, not published until the nineteenth century, also provided some expansion.
