Cairns City Council Chambers, Heritage-listed council chambers in Abbott Street, Cairns, Australia.

The Cairns City Council Chambers is an administrative building on Abbott Street featuring eight Ionic columns across its facade and a T-shaped floor plan. The interior contains offices, a strong room, the council chamber, and visitor areas, with the structure marked by scrolled brackets and a stylized pediment displaying the building's official name.

The chambers were designed by the Cairns partnership Hill & Taylor and built in 1929–1930 by contractor Alex McKenzie, replacing an earlier timber council chambers on the site. Mayor Alderman W. A. Collinson laid the foundation stone on 20 November 1929, when the work was estimated at about £15,000. Around 1961 the building was extended by three bays on each side with matching facade detailing.

The building represents civic pride during Cairns' transformation from a frontier town into a regional center, showing how the community invested in official architecture to assert its growing importance. The classical design signals how local governance was understood as a formal and ceremonial function worthy of monumental expression.

The former chambers now house the Cairns City Library, so entry follows library conditions rather than council business. The building sits on a large corner site at Abbott and Aplin Streets, surrounded by parkland, with the 1929–30 facade facing Abbott Street. The 1961 extension added three matching bays to each side, so compare the older central section with the later wings.

The foundation stone was laid by Mayor Alderman W. A. Collinson on 20 November 1929, when the building was estimated to cost about £15,000. The original T-shaped plan had a columned vestibule (pronaos) facing Abbott Street, flanked by three bays of verandah on each side, since enclosed. Around 1961 the building was extended by three matching bays to either side.
