The 2010–11 Nationalliga A was the 41st edition of the premier category of the Swisswomen's football national championship, organized by the Swiss Football Association. It took place from 7 August 2010 to 28 May 2011. Ten teams took part in the competition, with FC Saint Gallen replacing relegated Rapperswil Jona. It marked a reform in the competition system, with the introduction of a second stage comprising an eight-teams round-robin championship play-off and a promotion confronting the first stage's two bottom teams and the Nationalliga B's two top teams.
