Bald Hills is the northernmost suburb in the City of Brisbane, Queensland, Australia. In the 2021 census, Bald Hills had a population of 7,000 people.

Bald Hills is a largely residential suburb. It is mostly surrounded by bushland, but in the last few years some of the bush areas have been cleared to make way for new residential areas. It also borders onto the Bald Hills Flats – a large flood plain on the western side of the suburb that is used for cattle grazing. The South Pine River flows through the flood plain and forms the western border of the suburb. The South Pine River converges with the North Pine River and the combined flow, Pine River, forms the northern border. Along the banks of Pine River within Bald Hills is a large environmental park called the Tinchi Tamba Wetlands Reserve. The Pine River empties into Bramble Bay, between Redcliffe and Brighton.

The Bruce Highway goes between Bald Hills to Woree in Cairns and is 1,656 kilometres (1,029 mi) long.

The most prominent structure is the Bald Hills Radiator, the ABC's 198 metre tall AM radio transmission tower located on the eastern side of the suburb.

Bald Hills is situated in the Yugarabul traditional Aboriginal country.

The suburb is named after the two small hills in the South Pine River Valley floor.

The first land sales in the area occurred in 1857. Land sales around the Bald Hills railway station were advertised in April 1886. At the time the journey from Brisbane was described as "after travelling across the Downfall and Cabbage Tree Creeks, the traveller arrives at a long stretch of road, at the extremity of which rises a lofty knoll, round the brow of which the road winds, when the Bald Hills are reached".

In 1888, the "Bald Hills Railway Station Estate" made up of 500 allotments was advertised to be auctioned by Arthur Martin & Co., auctioneers. A map advertising the auction indicates that the land is situated near Bald Hills railway station and special trains will be provided on the day of the sale.
