Bagre is a genus of sea catfishes found along the Atlantic and Pacific coasts of the Americas from southern North America to northern South America. They are the only member of the subfamily Bagreinae. Currently, five species are described:

The earliest known fossil remains of Bagre are from the Early Miocene-aged Calvert Formation of Maryland, US and the Pungo River Formation of North Carolina, US. However, their exclusively American distribution, combined with the ancient divergences assumed among subfamilies of the Ariidae, suggest that the subfamily may have diverged from the Ariinae during the early-mid Cretaceous following the breakup of West Gondwana, isolating the Bagreinae around South America.
