One of the staples of the parade season, this krewe is named for the Greek god of oceans and fertile valleys.  Launched in 1949, the krewe has its beginnings with a group of St. Claude Ave. businessmen who wanted a Carnival parade for their neighborhood.  Though the parade now follows the standard Uptown route, Okeanos is known for its elaborately-costumed captain and king.  Always a creative krewe, they keep to a unique regent hierarchy.  Each year, the queen from the previous year marches with the king and the court.  That evening, in lieu of the traditional bal masque, a Coronation Ball is held, where the current queen will be chosen by lottery.  She will then reign over the krewe until her own farewell parade.

This krewe shares a Greek theme with the krewes of Adonis, Aphrodite, Argus,  Atlas,  Endymion, Hermes,  Iris,  Jason,  Morpheus,  Muses, Orpheus,  Pegasus, Proteus,  Morpheus,  Pygmalion,  Rhea, Sparta, and  Zeus.
