The Song of the Sea, also known as Az Yashir Moshe and Song of Moses, is a poem that appears in the Book of Exodus (Shemot). It is followed in verses 20 and 21 by a much shorter song sung by Miriam and the other women. The Song of the Sea was reputedly sung by the Israelites after their crossing the Red Sea in safety, and celebrates the destruction of the Egyptian army during the crossing, and looks forward to the future conquest of Canaan.

The poem is included in Jewish prayer books, and recited daily in the morning shacharit services.
