The city was named for the nearby Wenatchi Indian tribe. The name is a Salish word that means "river which comes [or whose source is] from canyons" or "robe of the rainbow." Awenatchela means "people at the source [of a river]." The city of Wenatchee shares its name with the Wenatchee River, Lake Wenatchee and the Wenatchee National Forest.
Wenatchee is known as the "Apple Capital of the World" due to the valley's many orchards, which produce apples enjoyed around the world. The city is also sometimes referred to as the "Buckle of the Power Belt of the Great Northwest."

Wenatchee is in the major railroad line of the Great Northern Railway (now BNSF Railway) to Seattle. It was once the eastern terminus of the Great Northern's electric operations (1928/1929-1956) on its New Cascade Tunnel route via the Chumstick Valley, which went all the way to Skykomish. Here, steam or diesel locomotives were changed or coupled to electric locomotives for this route. Today, Amtrak's Empire Builder serves the city.
