The Königsallee (German pronunciation: [ˈkøːnɪçsʔaˌleː] ⓘ; literally "King's Avenue") is an urban boulevard in Düsseldorf, state capital of North Rhine-Westphalia, Germany.

The Königsallee is noted for both the landscaped canal that runs along its center, as well as for the fashion showrooms and luxury retail stores located along its sides.

Nicknamed Kö (German pronunciation: [køː] ⓘ) by locals, the Königsallee is one of Germany's busiest upscale shopping streets.

The Eastern side of Königsallee is entirely commercial, with numerous upmarket flagship stores and block-internal shopping arcades leading to and from the boulevard.

Düsseldorf lost its independence to Prussia for most of the 19th and early 20th century, but the city remained an important international centre of the arts, and Königsallee its foremost boulevard.
