The Algebuckina Bridge is a Victorian era railway bridge south-east of Oodnadatta, on the Central Australian Railway in South Australia, and opened in January 1892. It was the longest bridge in South Australia until construction of the Seaford suburban rail line across the Onkaparinga River south of Adelaide in 2014. Of lattice steel construction, it comprises 19 spans each 100 feet (30 m) long. It was built by a team of around 350 men, working in extreme desert heat. Several graves are nearby, and one of them, David Saunders, died in January 1890 from “heart disease accelerated by heat apoplexy.”

The bridge crosses the floodplain of the Neales River, which is prone to seasonal flooding, and replaced a surface-level railway which was frequently washed away. After a severe flood in 1974, which almost reached the bridge decks, the line was closed in 1981 and a new route built 100 miles further west.
