Pierre de Dyerée, Petrus de Dierreyo, was the old dean of the Faculty and professor of theology.

In 1403 he is described as a prebendary canon of the church of Troyes, master of arts and theology, and had been regent in theology for ten years. The last mention of him is made in September, 1433.

On November 4, 1433, a service was celebrated for his soul at Saint Mathurin's and the Bishop of Meaux officiated en pontifical.
