The phantom shiner (Notropis orca) is an extinct species of fish. It was once endemic to the Rio Grande basin and ranged from central New Mexico to southernmost Texas and adjacent Tamaulipas. Once found in the warm water reaches of the Rio Grande (though never particularly abundant), no specimens have been collected in this range since 1949, and it is believed to be extinct in this area. The native range of the phantom shiner was the Rio Grande from Espanola downstream to Brownsville, Texas. In New Mexico, it was documented only in the reach from Espanola to Socorro.
