Elton Jantjies kicked a late drop-goal as the Barbarians came back from 28-7 down to beat Argentina 38-35.
Despite a Juan Manuel Leguizamon try, Matias Orlando, Ramiro Moyano, Pablo Matera and Sebastian Cancelliere scores put Argentina 28-7 up.
A penalty try and a score from Siya Kolisi reduced the deficit to 28-21.
Julian Montoya scored for Argentina, but Damian de Allende and Lood de Jager tries and Jantjies' late kick sealed a dramatic Baa-Baas win at Twickenham.
"It's a massive privilege representing this historic club. The guys just went out there and put everything on the line and it's good to get a win," said De Jager.
"One thing that's always guaranteed from a Baa-Baas side is team spirit."
The Barbarians, an invitational team that has been playing national sides on a regular basis since 1948, beat England in May.
South Africa's Rassie Erasmus was coach for the Argentina game, with a squad featuring current Springboks Eben Etzebeth, Handre Pollard and Tendai Mtawarira.
Barbarians captain Wyatt Crockett added: "It was amazing. We have had such a fun week."
Argentina captain Matera said: "This is not the way we wanted to end the tour. The result is not what we expected but it was a good year for us if you see it in general.
"We are growing a lot as a team and we are on a good path."
