Alec Baldwin is off the hook.

The Manhattan District Attorney’s Office has declined to prosecute the “30 Rock” star for his scuffle with a photographer, sources familiar with the case said tonight.

Baldwin encountered a Daily News photographer, Marcus Santos, on June 19 after the lensman spotted the actor leaving the City Clerk’s Office to get a marriage license, according to reports.

Santos told police that Baldwin punched him on the chin.

But prosecutors don’t believe a crime took place, the sources said.

“No charges will be brought. The matter has been dropped entirely,” a source told The Post.

“His conduct did not rise to the level of a crime.”

Baldwin’s lawyer, Alan Abramson declined comment, as did Baldwin’s spokesman, Matthew Hiltzik.

The DA’s Office declined comment on the matter.
