The 2013–14 La Liga season (known as the Liga BBVA for sponsorship reasons) is the 83rd since its establishment. The season began on 17 August 2013, and will end on 18 May 2014. Barcelona are the defending champions. As in the previous years, Nike provided the official ball for all matches, with a new Nike Incyte Liga BBVA model to be used throughout the season for all matches.
