Olasz (Croatian: Olas; German: Ahlaß) is a village and municipality (Hungarian: [[község]]) in Baranya County, Hungary.
The name of the village is ultimately a Hungarianised term derived from the German word walha which Hungarians otherwise use as a root for their exonym of Italy (Olaszország).

It previously was part of the Mohács Subregion but during the creation of districts in 2013, it became part of Bóly District.
During the census of 2011, the population was 627. The vast majority of the population claimed Hungarian ethnicity (87.4%), though 29% also claimed German ethnicity and 8.8% claimed Croatian ethnicity, and the municipality has a German and Croatian local minority self-government.
