In 1975 the urban district of Neuss lost its independent status and was merged into the Grevenbroich district, which was renamed to Kreis Neuss. On May 262003 it changed its name, and is now officially called Rhein-Kreis Neuss.
The coat of arms was continued from the district Grevenbroich. The lion in the right side comes from the city of Jülich. The black cross in the left comes from the Cologne coat of arms. Both the bishops of Cologne as well as the dukes of Jülich owned land of the Neuss district.
