Moominpappa at Sea (Swedish: Pappan och havet, literally "Pappa 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 is dissatisfied with his life in Moomin Valley, so he organises the family to set off on a journey to find a lighthouse in the sea. Once arriving there, they find it a desolate and lonely place, inhabited only by a very unfriendly fisherman.
