The name Adolf is a boy's name of Danish origin meaning "noble wolf". Adolf and is often added to lists like Names That Mean Noble and discussed in our forums with posts like "Love, Like, Lose -- Outlandish/Guilty Pleasures edition!".
From the experts:
Adolf may have been a Swedish royal name but the terrible dictatorship of Adolf Hitler has ruled out this name Adolf for any sensible parent. In the US last year, there were more than 100 boys' given the Spanish variation Adolfo and a handful given the old school Adolphus, but none named Adolf or Adolph....thank goodness.
