Stadionul Ilie Oană, Football stadium in Ploiești, Romania.

Stadionul Ilie Oană is a fully covered all-seater football stadium in Ploiești, built from scratch on the site of the old ground and opened in September 2011. It holds 15,500 seats and replaced a venue that had stood since 1937.

Built by the Ploiești municipality between 1934 and 1937, the stadium first had a reinforced concrete stand of 5,000 seats and a wooden stand for about 3,500 people. In the summer of 1955 the two ends and a second concrete stand were added in three months, and capacity reached 18,000, with crowds of 20,000–25,000 at times. Around 1980 more seats were added between the second stand and the perimeter fence. Demolition began in December 2009 and was completed in 2010; a new all-seater stadium opened on the same site in September 2011.

The stadium serves as home to FC Petrolul Ploiești and brings together local fans who gather to cheer for their team during matches. This role has made it an important gathering place for the city's sports community.

The venue gets crowded on match days, so arriving early helps you find good spots and avoid the rush. The location is walkable for visitors and offers parking nearby for convenient access.

The old stadium's record crowd was far above its official capacity: although listed at 18,000 seats, 20,000 to 25,000 people sometimes packed in. The ground was named after Ilie Oană, a Romanian international player and coach. Demolition began in December 2009 and was completed in 2010.
