In Norse mythology, Gillingr was a giant, uncle (father's brother) of Suttungr and Baugi and grandfather of Gunnlöð. In skaldskaparmál does Gilling figure as Suttung's father. Gilling and his wife were murdered by Fjalar and Galar. Gillingr is also a surname, although not very common.
Two dwarfs, Fjalarr and Galarr, invited Gillingr and his wife to pay them a visit. They asked Gillingr to come with them on their boat out to sea. The dwarfs rowed onto a shoal, and the boat capsized. As Gillingr could not swim, he drowned. The dwarfs, however, righted their vessel and came back to land. Gillingr's wife was distressed at the news; the dwarfs asked if she might feel better if she could look out to where the accident happened. The dwarfs had grown tired of her, however, and agreed to drop a millstone on her head as she walked out through the door; and so they did.
Suttungr vowed to get revenge and tied them to a rock that would soon be covered by the rising tide. The dwarfs begged to be let free and promised to give him the mead of poetry as a "thank you" for saving them. Suttungr agreed and received the mead of poetry as a result.
