Moominpappa at Sea (Swedish: Pappan och havet, literally "The father and the sea") is the seventh book in the Moomin books by Finnish author Tove Jansson. It is based primarily around the character of Moominpappa. It was first published in 1965. Moominpappa at Sea forms the basis of episodes 25 and 26 in the 1990 TV series. The original title is a loose reference to Hemingway novel The Old Man and the Sea, though this is not reflected in the translation.
