Justin Bieber didn't let his Canadianness get in the way of a bad ass tattoo ... 'cause the singer just got a symbol of American pride inked on his body.
Bieb got the ink job done after a concert last night in Sydney, Australia ... opting for an eagle tattoo on his left shoulder.
The singer posted photos of the session -- and we're no ornithologists, but best we can tell ... it's a bald eagle.
Sooo ... the USA just gave Biebs the bird?
