Triana (/traɪˈænə/) is a town in Madison County, Alabama, United States, and is included in the Huntsville-Decatur, AL Combined Statistical Area.

It purportedly was named after Rodrigo de Triana, the crewman who first sighted land while sailing with Christopher Columbus on their first voyage to the Americas.

For a time in the 19th century, it was a thriving riverport on the Tennessee River prior to the construction of the railroads.

Triana is located in southwestern Madison County at 34°35′20″N 86°44′56″W / 34.58889°N 86.74889°W / 34.58889; -86.74889 (34.5888265, -86.7489274),[8] on a bluff on the north bank of the Tennessee River.

In 1977, the EPA issued warnings that fish and waterfowl from the Huntsville Spring Branch had shown high levels of Dichlorodiphenyltrichloroethane (DDT) in their bodies.

[14] Two years later, the EPA began to investigate how the pollutant had contaminated the water supply of the area.

Lawsuits were filed against Olin Corporation by residents of Triana, as well as the United States Department of Justice.

[14][15] The water near Triana was monitored by the EPA from 1982–1995 to track the levels of DDT that was still in the Huntsville Spring Branch.
