Westwood is a census-designated place in Boyd County, Kentucky, United States.

A suburb of Ashland, the two areas are closely affiliated, sharing a ZIP code and bus system.

Westwood is located on a flat to hilly elevation just west of the Ohio River.

The flat elevation in which Westwood is located was created by the ancient Teays River.

The course of the river was altered due to glacial formations around two million years ago.

[citation needed] It resulted in many flat hill tops that are commonly found in Boyd and Greenup counties which are evident on aerial satellite imagery.

Outside of this ancient river bed, the terrain is "ridge and valley" as is typical in most of Eastern Kentucky.
