Il teorema di Wick è un metodo per ridurre uno sviluppo in derivate di ordine superiore a un problema di calcolo combinatorio. Prende il nome dal fisico italiano Gian Carlo Wick. Viene largamente usato in teoria quantistica dei campi per ridurre prodotti arbitrari di operatori di creazione e distruzione a sommatorie di prodotti di coppie di questi operatori. Questo permette l'uso del metodo della funzione di Green, e di conseguenza l'uso dei diagrammi di Feynman.
