Estadio Centenario is a stadium in the Parque Batlle of Montevideo, Uruguay, used primarily for staging football matches. It is owned by the Montevideo Department.

It is listed by FIFA as one of the football world's classic stadiums. On July 18, 1983, it was declared by FIFA as the first Historical Monument of World Football, to this day the only building to achieve this recognition worldwide.
