Kim Kardashian West's fight to free imprisoned grandmother Alice Marie Johnson is over -- President Trump has granted her clemency ... TMZ has learned.

Our sources tell us the Prez signed off on Wednesday, and Alice will soon be released from the Aliceville Correctional Facility in Alabama. We're told she's heading straight home to be with her family.

As we reported ... KKW met with Trump last week at the White House to talk prison reform and about Alice's case. She and her attorney, Shawn Holley, were working with Ivanka Trump and Jared Kushner for several months on Johnson's case.

Kanye's recent public support of Trump probably had some influence on 45's decision, as well.

The 63-year-old grandma's case became national news last year when Kim tweeted about it -- she was sentenced to life in prison without parole in 1997 on money laundering and drug conspiracy charges ... her first offenses.
