Bundesautobahn 52

 is an autobahn in western Germany. It starts at the Dutch-German border near the community of Niederkrüchten, district of Viersen. From Elmpt it runs northeast.
Its westernmost part serves as an important commuter route into Düsseldorf. The autobahn becomes Bundesstraße 7 shortly before the Rheinkniebrücke, which leads into the Düsseldorf city centre. Traffic of the A 52 is routed through the Düsseldorf city centre on the B 8 and B 1 secondary roads up to Düsseldorf-Mörsenbroich, where the A 52 becomes a road of its own again.
The autobahn has three parts:
A new connection from the Dutch border to Elmpt opened in May 2009. An extension connecting the interchange Essen-Ost with the interchange Gladbeck has been proposed for several years, but has not been built yet, due to the need for several kilometers of tunnels below densely populated areas.
