Guests at a hotel near Honolulu's airport found a suckling pig in the lobby, but it was not on the menu.
They called the Hawaiian Humane Society last week, when a five-week-old female pig was found running around the lobby.
It was unclear how the piglet ended up there.
Humane society spokeswoman Tasha Tanimoto said the pig is healthy and has been named Pukalani.
She will be available for adoption once she is a little older. Ms Tanimoto said the piglet is being bottle-fed by a volunteer.
Humane society officials are not sure of the pig's breed, but a veterinarian suspects she will grow to be quite large.
Pukalani has been getting attention on the humane society's Facebook page, where a duck is also advertised for adoption.
