Occamova britva (ili Ockhamova oštrica) je princip koji se povezuje sa Engleskim franjevačkim svećenikom Williamom od Ockhama.
U svom najjednostavnijem obliku, "Occamova britva" govori da količina pretpostavki treba biti što je moguće manja. U svakodnevnom jeziku, glasila bi
- "Ako imate dvije teorije koje predviđaju isto, odaberite jednostavniju."
Na primjer, uzrok za izgorijelo stablo može biti udar groma ili je neko dovezao posebnu mašinu do drveta i upotrijebio je za paljenje gornjih grana drveta, te je zatim posadio travu da prikrije tragove dovoženja mašine do drveta. Prema "Occamovoj britvi", udar groma je bolje objašnjenje jer zahtijeva manje pretpostavki.
