Council bosses have launched a campaign in a bid to keep parks in Castleford smoke free.
Wakefield Council launched the project at Savile Park last week.
It aims to reduce the amount of exposure to tobacco youngsters in the town are exposed to.
Coun Pat Garbutt, cabinet member for adults and health, said: “We hope that when local residents realise how uncommon it is to smoke in children’s play parks, it will simply become unacceptable for anyone to do so.
“We are keen to protect children from the harmful physical effects of second- hand smoke.”
The project has been launched at the town’s four council-owned parks as well as at Junction 32 shopping village.
Coun Garbutt added: “We know that children who grow up with a parent or a family member who smokes are three times more likely to smoke themselves.
“This campaign, with the backing of the local community, will reduce the exposure that children have to people smoking.”
The campaign was launched after a council survey showed nine out of ten park users in Castleford would prefer them to be smoke free.
