The Mid Yorkshire Hospitals NHS Trust made nearly £1.7m from staff and visitor car parking during a 12 month period.
The trust, which runs Pinderfields, Pontefract and Dewsbury hospitals, raised the cash between April 2017 and March 2018.
Figures revealed in a Freedom of Information response showed that a total of £1.1m was received from hospital workers parking at the sites, with a further £582,000 made from people visiting their relatives and friends.
The trust has previously said that all money made from car parking goes back into patient care.
Reports in the national media after Christmas said that around 40 per cent of hospital authorities across the country have raised car parking charges in the last year.
Visitor prices at Pinderfields, Pontefract and Dewsbury have remained the same since August 2015.
A one hour stay costs £2, while a two hour stay costs £2.80.
Leaving the car for up to four hours costs £5, while parking for up to 24 hours is £6.90.
For disabled drivers with a blue badge, a one hour stay costs £2, while any stay up to 24 hours is £2.80.
Iain Brodie, general manager of facilities at the trust,said: “Our patient and visitor daily parking charges have remained the same for over three years, and this includes a capped charge for blue badge holders.
“The money we receive from parking is reinvested back into the Trust, to the benefit of our patients and staff. It helps to fund the running of the free bus service the Trust provides between sites and the up keep and maintenance of the car parks.
“In addition, we have an extensive concessions policy in place for those patients, relatives and visitors who may use our parking facilities regularly over the period of one week.”
