Moryana (, ) is a female sea spirit in Slavic folklore, possibly a goddess. Moryana was a sea vodyanitsa and daughter of the Sea Tsar, and also, according to some beliefs, she ruled the winds. Sometimes the moryany/moryanki (plural; ; Polish: moriany) were said to be numerous spirits of the sea and a marine kind of rusalki, which posed a great threat to ships, but usually Moryana was represented as a single entity.
