The Gladiator star reportedly donated €5,000 to the organisation, as reported by broadcaster Rick O'Shea who runs the online club.
Thanking the "legendary actor" via Twitter, O'Shea revealed that the club had a "minor miracle" this year, as they raised over €30,000 this Christmas which was split between Dublin Society for the Prevention of Cruelty to Animals and the Peter McVerry Trust.
"It is the season and all," Mr O'Shea tweeted. "Thank you to the legendary Russell Crowe for the most bafflingly brilliant support of The Rick O'Shea Book Club Xmas Appeal, again!".
"I had thought we wouldn't make €25,000 this year, now we are over €30,000 and counting. That's €190,000 raised over the five years. The appeal stays open until the end of the year".
