The Brooklands Lagoon Boat Ramp provides water access to Brooklands Lagoon, an elongated tidal estuary near Brooklands, Christchurch. The lagoon stretches approximately 4.

5 kilometres long and up to 800 metres wide, covering around 270 hectares, with the Styx River draining into it near the mouth of the Waimakariri River. The ramp sits within a broader recreational area that includes a dedicated carpark.

Nearby, the Brooklands Boating Club offers ramp membership that includes access to the boat ramp and washdown facilities.

The lagoon is recognised as one of Canterbury's most significant tidal estuaries, supporting over 100 recorded bird species and more than 5,000 wetland birds at peak times, making it a notable destination for both boating and wildlife observation.
