Wepitanock (also known as Momojosbuck or Wettamozo or Aquawoce) (died after 1651) was an Eastern Niantic chief sachem in the area around Rhode Island and Connecticut.
Wepitanock was likely Canonicus' nephew and was the older brother of Ninigret with whom he shared power.
Wepitanock had at least one wife (whose name is unknown but who may have been a Pequot as she is referred to as a "stranger").
Roger Williams describes Wepitanock as Miantonomi's brother-in-law.
Wepitanock had at least four sons and one daughter, who married her uncle Ninigret.
