Barca signed off on 2017 with an emphatic 3-0 Clasico win over fierce rivals Real Madrid at the Santiago Bernabeu on Saturday.
Title holders Madrid, meanwhile, are a distant fourth, 14 points behind Barca, albeit with one game in hand.
"The FC Barcelona squad are now on their Christmas holidays," read a club statement. "The final whistle at the Bernabeu and the 3-0 victory over Real Madrid marked the beginning of the festive break for the players until their return to training on 30 December at 6.00pm CET.
"Luis Surez, Leo Messi and Javier Mascherano all have the club's permission to rejoin the rest of their team-mates on in the New Year on 2 January."
