Rockcliffe Park is a neighbourhood in Rideau-Rockcliffe Ward, close to the centre of Ottawa, Ontario, Canada. Established in 1864, it was an independent village from 1926 until it was amalgamated with the rest of the city, on January 1, 2001. As of 2011, it had a population of 2,021. In 1977 the entire village of Rockcliffe Park was designated a Heritage Conservation District. Rockcliffe Park is one of only three surviving nineteenth-century communities of its kind in North America. The other two, in the United States, are both recognized as national historic places.
