JH Djazaïr (Arabic: جيل هندسة الجزائر) is a defunct Algerian football club that was based in Algiers. The club was founded as CS DNC Alger (Arabic: نادي ديناميكية بناء الجزائر) and played its home games at the Stade Omar Hamadi in Bologhine. The club has existed since at least the 1972–73 season, when it reached the quarter-finals of the Algerian Cup. That is the earliest recorded mention of its existence.
