Johannes de Sacrobosco, gelegentl. Johannes Sacro Bosco oder John of Holywood (* um 1195; † 1256) war ein englischer Gelehrter, der an der Universität Paris lehrte.

Um 1230 veröffentlichte er sein bekanntestes Werk Tractatus de Sphaera. In diesem Buch diskutierte Sacrobosco den Platz der Erde im Universum. Sacrobosco war ein Vorkämpfer für die arabischen Methoden in der Mathematik. Er war einer der Ersten in Westeuropa, der die arabischen Ziffern benutzte.

Sacrobosco kritisierte den Julianischen Kalender in seinem Buch De Anni Ratione (1235).
