QHLAN 15 was the fifteenth edition of the long-running Swedish QuakeWorld LAN, held in Stockholm, Sweden, from November 3–6, 2011. The event brought leading European duel and team players together for four days of competition and community play.

The programme featured separate Gold and Silver 1on1 tournaments, an open 2on2 competition and two 4on4 tournaments: a traditional Pro bracket and a player draft. Rikoll won the Gold duel title, while Sajko won the Silver tournament.

QHLAN 15 was the final numbered edition before the series returned with QHLAN2017.
