Natsional Sofia

The National Sport Academy Stadium in Sofia holds 2,500 people.

The senior side was formed in 2023 and entered the B Regional Group (Sofia), the fifth tier. It won 25 of its 26 matches and drew the other. Promotion to the fourth tier followed in 2024. That year's Bulgarian Cup run ended in the preliminary round against Rilski Sportist. In 2025-26 National won the A Regional Group (Sofia). On 11 June 2026 it beat OFC Kostenets in the promotion playoffs, which took the club into the Bulgarian Third League (South-West division) for the first time.

The academy had been ahead of the senior team for years. By 2015 it was the largest in Bulgaria, and in 2017 it signed a partnership with Dinamo Zagreb. Its graduates now play in the capital and beyond. Kaloyan Strinski, a midfielder born in 2006, is at CSKA 1948, and the winger Vasil Kazaldzhiev, born a year later, is at Slavia Sofia. In the season the seniors won their group, the under-15s won the Elite Group in Sofia.

It began on 1 June 2003, when Blagomir Mutin, a coach who could not find a job, started an academy of his own.
