Garra widdowsoni, commonly known as the Iraq blind barb or Haditha cave garra, is a species of cyprinid fish endemic to underground water systems near Haditha in Iraq. Although traditionally placed in its own genus Typhlogarra, this is not supported by genetic evidence, leading to its move to genus Garra. This cavefish is considered critically endangered because of water extraction, which has lowered the groundwater level. Once abundant, a survey in 2012 found that it now was very rare. Another species from the same place, Caecocypris basimi, may already be extinct. The only other known cavefish in Iraq is Eidinemacheilus proudlovei.

It has been declining very rapidly for at least the last 30 years. This species has disappeared for 12 years until it was rediscovered in January 2024 after a local fisherman caught an individual, and soon after another individual was captured. While there are not enough data to identify the actual rate of population decline, it was once locally abundant but now almost absent.
