Paris Hilton -- SIGNS HUGE DJ CONTRACT

Paris Hilton's first major stint as an international club DJ was a huge success -- in fact, the legendary nightclub where Paris spent the past couple of months has already signed P for 2014, TMZ has learned.

Hilton has been a MAJOR draw this summer at Amnesia nightclub in Ibiza, Spain ... where she played to packed crowds on a weekly basis at the club's famous "Foam & Diamonds" parties.

We spoke to the owner of the club who admits he was "nervous" when he first signed Hilton earlier this year -- but his fears were alleviated quickly when she stepped in to the booth ... and the crowds went insane.

"The number of people attending kept on growing and the positive word of mouth in Ibiza was just phenomenal," the owner tells us.

Paris flew back to L.A. on Thursday, bragging that she "killed it" -- and said her Ibiza success is already translating into tons of offers.

It's unclear how much cash Paris will rake in for the 2014 gig -- but we're told it's not really about the money, Paris just wants to prove she can hang with the big boys.
