The Boolboonda Tunnel is an abandoned heritage-listed railway tunnel near Mount Perry in Queensland, Australia. The tunnel is 192 m in length making it the longest unsupported man-made tunnel in Queensland. Its construction represented an important engineering feat for rail transport in Queensland.
The tunnel was constructed for the Bundaberg to Mount Perry railway line that was built in the 1880s. It passes under the Boolboonda Range through hard granite rock. It took two years to dig and was officially opened on 2 November 1883. The line was closed in 1960 and tracks removed the following year.
