Fimafeng (meaning "quick service" or "handy service") was a servant of Ægir and Rán in Norse mythology. He served alongside Eldir at the banquet depicted in the Lokasenna. During the banquet, he was praised so much he evoked the jealousy of Loki, who killed him. This resulted in Loki having to flee the banquet for a while. When he returned, Loki exchanged insulting remarks with the gods until he was scared off by Thor.
