The Argentine continues to rewrite the club's history books as his strike on Saturday means he has now beaten the Brazil legend's record of 34 goals during the 1996-97 campaign.
The Argentine's first-half strike against the islanders means he has now scored 35 times in the league this term, overtaking Ronaldo's previous high of 34 during the 1996-97 campaign for the Blaugrana.
Messi equaled Ronaldo's overall mark in 2009-10, and last season scored 53 goals in all competitions, surpassing the Brazilian's haul of 47 in the process.
The 24-year-old is now on course to beat Real Madrid attacker Cristiano Ronaldo's return of 40 goals last term, currently the highest by any player in a Liga campaign.
It has been a year to remember for Messi, who also became Barcelona's leading scorer of all time earlier this week and the first player to score five goals in one Champions League match as he netted a quintuple against Bayer Leverkusen recently.
