Septemvri Stadium, Football stadium in Sofia, Bulgaria.

Septemvri Stadium is a multi-purpose stadium in Sofia's Krasna Polyana district, used mainly for football by PFC Septemvri Sofia. Opened in 1958 with 25,000 seats, it also had basketball and volleyball halls, tennis courts and athletics facilities. The ground has been disused for matches since the 2000s.

Septemvri Stadium is the third home of FC Septemvri, founded in 1944. Built with state funding near the club's previous Razsadnika pitch, it opened on 18 May 1958 with a 2:2 friendly against Hungary's Vasas, following a youth match between Septemvri and Levski. During the 1969–1988 merger with CSKA it hosted mainly friendlies and Soviet Army Cup ties, and from 1981 to 1984 CSKA Septemvriysko Zname II played its home games there.

The name Septemvri means September, the month of Bulgaria's 1944 communist takeover, and the club and ground carry it. The stadium opened on 18 May 1958 with a day-long sports programme for the Krasna Polyana neighbourhood, including a youth match between Septemvri and Levski and a 2:2 friendly between the Septemvri first team and Hungary's Vasas.

The stadium stands in Krasna Polyana, southwest Sofia, near 57 Secondary School. It has been closed to matches for years and is not in use, so there is no event timing to plan around. Septemvri's first team plays home games at Stadion Dragalevtsi, and the youth school uses the renovated pitch by the school.

In 2011 Hristo Stoichkov brought in Spanish investors for a new 15,000-seat stadium on the old ground, to be called The Crown of Septemvri; the project was cancelled in 2013. A later DIT Group plan of 2018, for 4,500 seats, was still unbuilt as of 2023.
