US Pianese is an Italian football club based in Piancastagnaio, a comune in the province of Siena, Tuscany. The club competes in Serie C, the third tier of Italian football, which is a fully professional league divided into three geographical groups. Their full name, Unione Sportiva Pianese, reflects their sporting union, and they play their home matches at the Stadio Comunale di Piancastagnaio. Founded in 1928, the club has spent much of its history in the regional amateur divisions (Eccellenza and Serie D) before achieving the historic promotion to Serie C. This placed them among Italy's professional clubs, a monumental achievement for a team from a small town. Their colors are likely red and blue.
