Hinckley was released from St. Elizabeths Hospital, the Washington Post reported, citing his lawyer Barry Levine, who had confirmed that his client would leave in the morning, and a witness on the sprawling hospital campus.
Phyllis Jones, a spokeswoman for the city's Department of Behavioral Health, told AFP that "all discharges planned for today have taken place" but said she could not comment on specific patients.
Levine was not immediately available for comment when contacted by AFP.
Since the 1990s, Hinckley has been permitted gradually longer supervised home visits with his mother, lasting up to 17 days. Secret Service agents have tracked him during each trip.

Hinckley, who was declared not guilty on grounds of insanity, said after the March 30, 1981 shooting outside a Washington hotel that he wanted to kill Reagan to impress actress Jodie Foster, whom he became obsessed with after watching the film "Taxi Driver."
Daughter Patti Reagan Davis wrote on her website in 2015 that "I hope the doctors are right when they say that John Hinckley isn't a danger to anyone, but something in me feels they are wrong."
One thing troubling her, she said, was that while at St. Elizabeths, Hinckley had written to convicted mass murderers Ted Bundy and Charles Manson.
But Levine has argued since 2003 that evaluations by the hospital's officials showed that Hinckley no longer posed any threat.
Three other men, including Reagan press secretary James Brady, were badly wounded in Hinckley's attack.
When Brady died in 2014, a medical examiner attributed his death to the injuries received 33 years earlier, but no additional charges were filed against Hinckley.
The court order places dozens of detailed conditions on Hinckley's "full-time convalescent leave" from St. Elizabeths, including a ban on contact with Foster, but said they can be phased out after a year to 18 months if he continues to make progress.
