Reinhold Tiling (13 June 1893 – 11 October 1933) was a German engineer, pilot and rocket pioneer.
A flier in the First World War and later flight director of an Osnabrück airfield, he took up rocketry in the late 1920s and built solid-propellant rockets, patenting a chamber rocket in 1928.
In 1931 he launched what has been called the first German postal rocket. Tiling died in 1933 of burns suffered when powder exploded in his rocket workshop near Bad Essen
The lunar crater Tiling is named after him.
