Rudolph Wilde (born 26 May 1857 in Deutsch Krone (West Prussia) (today Wałcz, Poland); died 1 November 1910 in Schöneberg, German Empire) was a German local politician and Mayor of the then independent city of Schöneberg, now a part of Berlin.
His term in office, which ended with his death in 1910 saw a rapid rise in the population of Schöneberg as many people moved into the rapidly growing greater Berlin area to work in the newly emerging industrial jobs.
To manage this growth and to cope with the rising population, Wilde was among the first proponents of a subway line in Schöneberg, which was built in just two years (1908–1910) using municipal funds as the de:Hochbahngesellschaft was unwilling to invest private capital into what it deemed a low-profit enterprise.
The subway line thus became the first in Germany built on behalf of the public sector and opened a month after his death.
It is today U4 of the Berlin U-Bahn network.
