John Martyn (died 1473), also known as John Marten, was a Master of University College, Oxford, England.[1][2]
Martyn was a Fellow at University College from 1427. As the Senior Fellow of the College, he became Master in 1441, a post he held until his death in 1473. This was a long time (32 years), especially for the period. It is probably the longest period at any Oxford college before 1500.[2] During his time as Master, University College attained its first quadrangle or "quad".
