Roch (lived c. 1348 – 15/16 August 1376/79; traditionally c. 1295 – 16 August 1327), also called Rock in English, is a Catholic saint, a confessor whose death is commemorated on 16 August and 9 September in Italy; he is especially invoked against the plague. He has the designation of Rollox in Glasgow, Scotland, said to be a corruption of Roch's Loch, which referred to a small loch once near a chapel dedicated to Roch in 1506.

He is a patron saint of dogs, invalids, falsely accused people, bachelors, and several other things. He is the patron saint of Dolo (near Venice) and Parma, as well as Casamassima, Cisterna di Latina and Palagiano (Italy). He is also the patron saint of the town of Albanchez, in Almeria, southern Spain.

Saint Roch is known as "São Roque" in Portuguese, as "Sant Roc" in Catalan, as "San Roque" in Spanish (including in former colonies of the Spanish colonial empire such as the Philippines) and as "San Rocco" in Italian.
