Richard Ullerston DD (died August or September 1423) was a Vice-Chancellor and Chancellor of Oxford University.
Ullerston was born in the Duchy of Lancaster, England. Having been ordained priest in December, 1383, he became a Fellow of Queen's College, Oxford (1391–1403), holding office in the college, and proceeding to Doctor of Divinity and Vice-Chancellor of Oxford University in 1394. In 1408, he became Chancellor of the University and in the same year wrote at the request of the Bishop of Salisbury a sketch of proposed ecclesiastical reforms: "Petitiones pro ecclesiae militantis reformatione".
Ullerston wrote a commentary on the Creed (1409), one on the Psalms (1415), another on the Canticle of Canticles (1415), and "Defensorium donationis ecclesiasticae", a work in defence of the donation of Constantine. At the request of Archbishop Courtenay he wrote a treatise, "De officio militari" 'On the military office', addressed to Henry, Prince of Wales.
From 1403, Ullerston held the prebend of Oxford in Salisbury Cathedral, and from 1407 the rectory of Beeford in Yorkshire.
