Kalbarri is a coastal town in the Mid West region located 592 km (368 mi) north of Perth, Western Australia. The town is located at the mouth of the Murchison River, which has an elevation of 6 metres (20 ft). It is connected by public transport to Perth via Transwa coach services N1 and N2.

Kalbarri is a part of the traditional lands of the Nanda people who were recognised as the traditional owners of more than 17,000 square kilometres (6,600 sq mi) of land and water in the Yamatji region, in Western Australia, on 28 November 2018. Nanda people have been awarded exclusive native title rights over several key areas including Paradise Flats, Bully, Wilgie Mia, Mooliabatanya and Syphon pools.

The story of the Beemarra serpent is the central dreaming story of Nanda people. The Beemarra is, according to Nanda culture, an ancestral being responsible for the creation of the land and waters in the region

Kalbarri was named after an Aboriginal man from the Nanda tribe and is also the name of an edible seed.

The cliffs near the river mouth were named after a trading ship, the Zuytdorp, that was wrecked there in 1712.

The area became a popular fishing and tourist spot in the 1940s and by 1948 the state government declared a townsite. Lots were soon surveyed and the town was gazetted in 1951.

In April 2021 the town suffered serious damage from Tropical Cyclone Seroja.

The town is geared towards tourism and fishing, with attractions including the daily pelican feeding, the Kalbarri National Park, Murchison River Gorge and the Murchison River. There are two charter boats to go on to view the Murchison River. The town attracts 200,000 tourists every year, with the population of the town swelling to 8,000 during holiday seasons. Electricity to the town and hotels is supplied by a fragile 33kV power line from the central grid. To increase grid stability, a 5MW/2MWh grid battery is installed.

The Kalbarri National Park is home to a phenomenon of geography and geology known as the Z Bend, a tourist lookout, and "Nature's Window", a rock formation overlooking the Murchison River. Red Bluff and other coastal cliffs and formations are located south of the town. The Rainbow Jungle (The Australian Parrot Breeding Centre), was severely damaged by the 2021 cyclone and is permanently closed.
