As of my last update in January 2022, Lionel Messi held the title of the all-time leading goal scorer for FC Barcelona. Messi, an Argentine forward, played for Barcelona from 2004 to 2021, during which he scored a remarkable number of goals, breaking numerous records. However, please note that my information might be outdated, so I recommend verifying with the latest sources in case there have been any changes since then.
