The 2010–11 La Liga season (known as the Liga BBVA for sponsorship reasons) was the 80th since its establishment. The campaign began on 28 August 2010 and ended on 21 May 2011. A total of 20 teams contested the league, 17 of which already contested in the 2009–10 season and three of which were promoted from the Segunda División. In addition, a new match ball – the Nike Total 90 Tracer – served as the official ball for all matches. The most significant managerial change prior to the start of the season was two-time Champions League-winning José Mourinho taking over at Real Madrid.
