Wilhelm Adam (15 September 1877 – 8 April 1949) was a German general who served in the Bavarian Army, the Reichswehr and the Wehrmacht.

During World War I, Adam fought as a company leader of a Bavarian pioneer unit, but only for a short period.

But right at the end of the war he was back to being a Bavarian engineer unit leader.

With the end of the war, Adam served in various posts within the Reichswehr, from posts such as a liaison officer to the Bavarian Military Ministry and being an infantry battalion commander, in the 20th Infantry Regiment.

Adam's unpublished memoir was preserved for many years after the war in a Bavarian monastery.
