Pianoro (Bolognese: Pianôr) is a town and comune in the province of Bologna in the Emilia-Romagna region of Italy, in the hills of the Tusco-Emilian Apennines, 200 metres (660 ft) above sea level.

According to legend the Etruscan king Ocno (also known as Bianore, mythical founder of Felsina and other cities), lived in the area.

The Gothic Line was very close and in October 1944 there was a huge battle (in Livergnano) involving German, American forces and local partisans, leaving on the ground thousands of Anglo-American soldiers.

Industries located in the area are primarily in the mechanical engineering and packaging (Marchesini Group, Romaco, MG2) and chemicals (Sayerlack S.r.l., part of Sherwin-Williams) sectors The Gessi Bolognesi e Calanchi dell'Abbadessa Park, shared with San Lazzaro di Savena, contains an area of karstic topography with dolines, badlands and cliffs.

TPER bus services offer frequent connections to/from Bologna, San Lazzaro di Savena and Monghidoro.
