The use of single-use plastic across all catering will be cut as part of a drive to reduce waste and help the environment, it was reported in The Telegraph.
The move will affect staff and patient canteens, on-ward catering and plastics handed out by on-site retailers including Boots, M&S and WH Smith.
The NHS bought at least 163 million plastic cups, 16 million pieces of plastic cutlery, 15 million straws and two million plastic stirrers last year, NHS data shows.
NHS England said if the health service can cut its use of catering plastic in half, it could mean more than 100 million fewer items each year being used.
NHS England chief executive Simon Stevens said: "It's right that the NHS and our suppliers should join the national campaign to turn the tide on plastic waste.
"Doing so will be good for our environment, for patients and for taxpayers who fund our NHS.
"We're pleased that as a first step, major retailers operating in hospitals have committed to cut their plastics, starting with straws and stirrers, cutlery, plates and cups."
The NHS has written to hospitals urging them to back the campaign, sign the pledge and curb plastic waste.
Ruth May, chief nursing officer for England, said: "Across the NHS, nurses, midwives and other frontline staff are providing great leadership on environmental issues and championing sustainability where they work.
"Support from local NHS organisations to sign the pledge and cut use of catering plastics will need all NHS staff to take action in their own areas and encourage their employers to go further faster."
