The Irving Nature Park is a free park in Saint John, New Brunswick, Canada, close to the nearby urban centre, only minutes away from the uptown area. This environmental retreat was developed with the intention of protecting the environment. It encompasses a total of 243 ha and is sandwiched between a salt marsh and the Bay of Fundy. The park is owned and operated by JD Irving and is open annually from May through October for motor-vehicle traffic. In 2011, Irving Nature Park became the first park to be designated as an Urban Star Park by the Royal Astronomical Society of Canada.
