Carl Theodor (Thede) Palm (27 September 1907 – 18 February 1995) was a Swedish historian of religion, director of research and head of military intelligence.

He was librarian at the Lund University Library from 1938 to 1956 and he was head of department at the Swedish National Board of Information (Statens Informationsstyrelse) from 1943 to 1944 as well as being an expert there in 1945.

[1] In 1943, Palm put in a request for a leave of absence[3] to operate under Carl Petersén at C-byrån, a secret intelligence organization within the Swedish Armed Forces during World War II.

[4] In his posthumous notes he tells how he was subjected to American pressure that the Swedish intelligence service should be practically under direct CIA command, which Palm firmly resisted.

[5] In 1965 the foreign-oriented T-kontoret was merged with the domestic-oriented B-kontoret (B-office) and became the Defence Staff's Special Bureau (Försvarsstabens särskilda byrå), more commonly known as IB.
