Georg Rudolf Weckherlin (15 September 1584 – 13 February 1653) was a German poet and diplomat. Influenced by the French La Pléiade, his poetry introduced Renaissance forms and themes previously unknown in German verse. In his political career, Weckherlin worked in the service of the Electorate of the Palatinate, serving on diplomatic missions to France and England. Weckherlin would eventually come to be employed by the English crown as an expert on foreign languages and cryptography, and continued to serve in this position in the Commonwealth of England.
