Wamsutta (c. 1634–1662), also known as Alexander Pokanoket, as he was called by New England colonists, was the eldest son of Massasoit (meaning Great Leader) Ousa Mequin of the Pokanoket Tribe and Wampanoag nation, and brother of Metacomet.

Wamsutta was born circa 1634, as the eldest son of Massasoit Ousa Mequin, leader of the Pokanoket. Wamsutta married Weetamoo.

After Massasoit's death, Wamsutta assumed leadership of the Pokanoket, becoming leader of all the Native American tribes between the Charles River in Massachusetts and Narraganset Bay in Rhode Island, including the tribes in eastern Rhode Island and eastern Massachusetts. Wamsutta, whom the English named Alexander, agreed to adhere to the peace established by his father. As a result of a collapse of the fur trade, he substantially increased the power of the Pokanoket by selling land to colonists. However, rumors soon began to circulate that he was conspiring with the Narragansetts to attack the English. In 1662, the English accused Wamsutta of independently negotiating land sales. In 1662, he was summoned to and seized by the Plymouth Court. After being questioned, Wamsutta became ill and soon died.

The cause of death was disputed, and Wamsutta's brother Metacomet (who succeeded Wamsutta in leadership of the Pokanoket) suspected that he had been poisoned. Wamsutta's death was one of the factors that would eventually lead to the 1675 King Philip's War. Some historians^[who?] believe Wamsutta was poisoned or tortured by Governor Josiah Winslow, who saw him as a threat; however, considering Winslow's father, Edward Winslow, and Governor William Bradford (both of whom had died before this), and their previous peaceful relations with Wamsutta's father, Massasoit, such speculation is open to question. This issue is examined in the 2017 historical novel "My Father's Kingdom" by James W. George.

Metacomet (or Metacom), known as King Philip to the colonists and officials at Plymouth, signed an agreement with the English in 1662. Like Wamsutta and his father before him, Philip vowed not to needlessly or unjustly provoke or raise war with any other natives. In return, the colonists agreed to advise and aid Philip. However, it was an uneasy alliance, and hostilities between natives and colonists continued to grow.
