Thomas Kielinger OBE (born July 1940 in Danzig) is a German journalist, political commentator and author, who for a long time used to be London correspondent for Die Welt.

In 1977, he was made Die Welt's chief correspondent in Washington DC to coincide with the inauguration of the United States President Jimmy Carter, and later in the era of Ronald Reagan.

Several books testify to his abiding interest in Anglo-German history: Crossroads and Roundabouts: Junctions in German-British Relations (1997), Großbritannien, a country portrait as part of a series called "Die Deutschen und ihre Nachbarn" (The Germans and Their Neighbours, 2009; revised edition 2016), as well as a biography of the Queen, Elizabeth II – Das Leben der Queen (2011; dtv paperback 2014).

The latter was also favourably reviewed in The Times Literary Supplement, where it was stated that "amid all the warm words about the Queen's commitment to duty, it is Thomas Kielinger who comes closest to explaining what motivates Elizabeth II".

[2] In 2014, Kielinger added another biography to his list of publications: Winston Churchill – The Late Hero, which reached its 5th edition in 2015 and is available in paperback, as well as in an audio version (11 CDs), read by performer and author Gerd Heidenreich.
