The Nindooinbah Dam is a decommissioned earth-fill embankment dam with an un-gated spillway located off-stream in the South East region of Queensland, Australia. The sole purpose of the dam is for recreation.

Located near the town of Beaudesert in the Scenic Rim region, the Nindooinbah Dam was completed in 1951 and decommissioned following a review by the dam operator, SEQ Water, that assessed that the dam did not meet the required standards set by regulators. Whilst there were no published concerns with the dam's safety, the small capacity of the reservoir, at 322 megalitres (71×10^ imp gal; 85×10^ US gal), meant that decommissioning of the dam did not impact on the region's water security.

Non-powered boating is permitted on Nindooinbah Dam and public access is available to the dam wall embankment area.
