Wilson Granger was a male Human and the Prime Minister of the Mariposa colony in the 24th century. He was a clone of Captain Walter Granger, the commanding officer of the SS Mariposa and founder of the colony.

In 2365, he and several Mariposans were experiencing replicative fading due to being cloned several times over. After a brief attempt at stealing DNA from the USS Enterprise-D's crew, the Mariposans were reunited with the Bringloidi of the Bringloid V colony who were also transported by the Mariposa in 2123. Granger initially had misgivings due to the Bringloidi's "repugnant" nature, but accepted it when the Enterprise crew would not give their DNA, and that they now had enough of a genetic base to create a stable society. (TNG: "Up The Long Ladder")

Wilson Granger was played by actor Jon De Vries.
