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.

[1][2] Although traditionally placed in its own genus Typhlogarra, this is not supported by genetic evidence,[3][4] leading to its move to genus Garra.

[2] This cavefish is considered critically endangered because of water extraction, which has lowered the groundwater level.

[1] Once abundant, a survey in 2012 found that it now was very rare.

[1] Another species from the same place, Caecocypris basimi, may already be extinct.
