Praepositinus (Gilbert Prevostin of Cremona, Prevostinus Cremonensis) (c. 1135 – 1210) was an Italian scholastic philosopher and theologian. He was a liturgical commentator, and supporter a res-theory of belief. He discussed intentional contexts. Having studied under Petrus Comestor and taught at Paris, he went to Mainz Cathedral in 1196. Returning, he was Chancellor of the University of Paris from c. 1206 to 1209. A Summa contra haereticos from around 1200 was once attributed to him.
