Dionysus' cabin (#12) is the cabin that houses Dionysus' demigod offspring at Camp Half-Blood. There is only one known camper currently living in there.
The cabin's roof and walls are lined with grape vines. It has only two known occupants so far. Its relatively small number of demigods is possibly due to his strong dedication to his wife at Olympus.
