Aleșd (Romanian pronunciation: [aˈleʃd] ⓘ; Hungarian: Élesd, Slovak: Alešď) is a town in Bihor County, western Romania.

Consequently, it is served by frequent rapid and intercity (IC) trains from Cluj-Napoca, Bucharest, Arad, and Timișoara.

In the first half of the 18th century, the population moved to the terrace on the right bank of the Crișul Repede, in the place that it occupies today.

As a result of the Second Vienna Award, it was returned to Hungary in August 1940, staying under Hungarian administration until October 1944, towards the end of World War II.

In 1968, the old territorial division into județe was reinstituted, and the Aleșd reverted to being part of Bihor County, and was declared a town that year.
