WWE star Jack Swagger was arrested last night in Mississippi, TMZ has learned -- after allegedly driving under the influence ... with pot in his car. Sources close to the situation tell TMZ, Swagger -- real name Jacob Hager -- was leaving a "Smackdown" taping at Mississippi Coast Coliseum in Biloxi when he was pulled over for speeding.According to law enforcement, the officer who pulled him over determined Swagger was driving under the influence -- and a search revealed Swagger was in possession of marijuana.

We're told Swagger -- a former WWE World Heavyweight champ -- was taken in by local police officers ... and later released on his own recognizance.

He has been charged with DUI (not alcohol), marijuana possession, and speeding -- all misdemeanors.

We reached out to WWE, who tells TMZ, "Mr. Swagger is responsible for his own personal actions."
