Peter Sutcliffe is serving life for the murders of 13 women
Sutcliffe, 61, was said to have been stabbed in the face by a fellow patient at Broadmoor, Berkshire.
The hospital confirmed there was an attack on a patient on Saturday and the police have been informed.
Sutcliffe, a lorry driver from Bradford who was jailed for life in 1981 for 13 murders, is already blind in one eye after a previous attack.
A spokesman said: "Occasionally there are incidents where one patient assaults another and those incidents are dealt with accordingly."
He added the patient's injuries were not serious.
