Capital Circle is a circular road surrounding Capital Hill in the centre of Canberra, Australia's capital city. It is one of three concentric roads on the hill, with State Circle the outermost and Parliament Drive the innermost. There are no buildings on Capital Circle. Parliament Drive surrounds New Parliament House.

Roads named for each of Australia's state capitals converge at Capital Circle or State Circle. The main roads leading from the circle are Commonwealth Avenue to the north and Canberra Avenue and Adelaide Avenue to the south.
