Cordova (/kɔːrˈdoʊvə, ˈkɔːrdəvə/) is a small town located near the mouth of the Copper River in the Valdez-Cordova Census Area, Alaska, United States, at the head of Orca Inlet on the east side of Prince William Sound. The population was 2,239 at the 2010 census, down from 2,454 in 2000. Cordova was named Puerto Cordova by Spanish explorer Salvador Fidalgo in 1790. No roads connect Cordova to other Alaskan towns, so a plane or ferry is required to travel there. In the Exxon Valdez oil spill of March 1989, an oil tanker ran aground northwest of Cordova, heavily damaging ecology and fishing. It was cleaned up shortly after, but there are lingering effects, such as a lowered population of some birds.
