Health Minister James Reilly is proposing to extend the smoking ban to a wide range of outdoor areas.
Under his proposals, smoking would be banned in places such as public parks and beaches.
The Minister said said he wanted to go a step further than the proposed ban on smoking in cars with children so that smoking can be 'denormalised'.
He said he would favour implementing as similar ban on smoking in parks and on beaches to that which operates in New York.
Dr Reilly was speaking at an Irish Heart Foundation conference in Dublin yesterday.
A workplace smoking ban, which includes pubs and restaurants, has been in place in Ireland since 2004. More recently, some hospitals have also banned smoking in the grounds outside their buildings.
