In 1950, Speidel was one of the authors of the Himmerod memorandum which addressed the issue of rearmament (Wiederbewaffnung) of the Federal Republic of Germany after World War II.
 As an important military adviser to the government of Konrad Adenauer, he was instrumental in the creation of the Bundeswehr, and later as a four-star general (the first to be awarded this rank by the Bundeswehr, together with Adolf Heusinger), he oversaw the smooth integration of the Bundeswehr into NATO.

According to an article in Der Spiegel, which cited documents released by the Bundesnachrichtendienst in 2014, Speidel may have been part of the Schnez-Truppe, a secret illegal army that veterans of the Wehrmacht and Waffen-SS established up from 1949 in Germany.

After the war Speidel served for some time as professor of modern history at Tübingen and in 1950 published his book Invasion 1944: Rommel and the Normandy Campaign before being involved in both the development and creation of the new German Army (Bundeswehr) which he joined, reaching the NATO rank of full general.
He was subsequently appointed Supreme Commander of the Allied NATO ground forces in Central Europe in April 1957, a command that he held until retirement in September 1963.
His headquarters were at the Palace of Fontainebleau in Paris.

In 1960, Speidel took legal action against an East German film studio which portrayed him as having been privy to the assassinations of King Alexander I of Yugoslavia and French Foreign Minister Louis Barthou in 1934, as well as having betrayed Field Marshal Erwin Rommel to the Nazis after the 20 July Plot in 1944.
He successfully claimed damages for libel.
Hans Speidel died in 1984 at Bad Honnef, North Rhine-Westphalia, aged 87.
