Vaba tarkvara laul

"Vaba tarkvara laul" (inglise keeles "Free Software Song") on Richard Stallmani rahvamuusikast inspireeritud laul (filklaul), mis räägib vabast tarkvarast. 

Laulu meloodia pärineb bulgaaria rahvalaulust "Sadi moma bela loza" (ligikaudne tõlge 'tüdruk istutab viinamarju'). Stallmann kirjutas laulu 1993.

Hoarders can get piles of money,
That is true, hackers, that is true.
But they cannot help their neighbors;
That's not good, hackers, that's not good.

When we have enough free software
At our call, hackers, at our call,
We'll kick out those dirty licenses
Ever more, hackers, ever more.
