An Anglo-Saxon Dictionary is a dictionary of Old English (also known as Anglo-Saxon). Four editions of the dictionary were published. It has often (especially in earlier times) been considered the definitive lexicon for Old English. It is often referred to by the names of its compilers, for example Bosworth or Bosworth & Toller.

Editions
