A spokesman for Peterborough and Stamford Hospitals this morning said Atkinson was in a stable condition after being admitted last night.
It has not been confirmed when he will be ready to leave the hospital's care.
Atkinson is believed to have suffered a shoulder injury after his high-performance car crashed on the A605 in Haddon, Cambridgeshire.
The 56-year-old Mr Bean actor was reportedly driving a McLaren F1 supercar when it spun around several times, ran into a tree and a lamppost and caught fire.
The actor is said to have walked from the vehicle and was with a passing motorist until emergency services arrived.
A spokesman for the star has not yet commented on the incident.
Atkinson, known to be a car enthusiast, recently topped the leader's board on Top Gear's Star in a Reasonably Priced Car contest.
He told presenter Jeremy Clarkson he was keen on racing and was currently driving a 1964 Ford Falkan.
Atkinson is best known for his work on Not The Nine O'Clock News, Blackadder and Mr Bean, in which his hapless character drives an old Mini.
