West was sentenced to two years of probation, 24 anger management therapy sessions and 250 hours of community service.
West entered the plea through his attorney and did not attend the court hearing Monday.
The rapper did not reach a civil settlement with the paparazzo, and his plea cannot be used against him in a civil lawsuit.
West was charged with misdemeanor counts of battery and grand theft after an altercation at LAX with photographer Daniel Ramos in July.
Ramos claimed West punched him in an unprovoked attack and wrestled his camera to the ground during the scuffle.
