Vincent Keoni Manuwai (July 12, 1980 – November 4, 2018) was an American professional football guard.

He attended Farrington High School in Honolulu, where he earned varsity letters three times each in football and track and field and once in basketball.

Through the 2007 season, Manuwai started all but one game for the Jaguars and was the most successful player on the offensive line.

He recovered the starting spot when Smiley was injured in October and became a significant factor in the emergence of Jacksonville's formidable running game.

[5] Manuwai died on November 4, 2018, at the age of 38, after reportedly collapsing while moving into an apartment in Honolulu, Hawaii.
