There sure is. By the time I type this up, someone will undoubtedly have beaten me to it, but here it is anyway:

Ionian -- WWHWWWH (major scale)
Dorian -- WHWWWHW
Phrygian -- HWWWHWW
Lydian -- WWWHWWH
Mixolydian -- WWHWWHW
Aeolian -- WHWWHWW (minor scale)
Locrian -- HWWHWWW

Just to clarify, W means whole step (two semitones) and H means half step (one semitone).

EDIT: I'll be darned, no one beat me to it!
