Suarez leapfrogged Kubala with his 195th Barca goal from 278 appearances in Thursday's (AEST) 1-0 win over LaLiga rival Espanyol.
The 33-year-old forward broke the deadlock in the 56th minute to move Barca within a point of leaders Real Madrid, while relegating Espanyol.
Suarez already eclipsed Josep Samitier's 184-goal haul in October, with only two players above him – superstar captain Lionel Messi (630) and Cesar (232).
Since arriving from Premier League giant Liverpool in 2014, Suarez has flourished and even contributed 97 assists for Barca.
Suarez has won four LaLiga titles, the Champions League, UEFA Super Cup and Club World Cup among other honours at Camp Nou.
