- For other uses of this name, see Stillwell.
Stillwell was a male Starfleet captain in the 2160s.
In 2161, Stillwell offered then-Ensign Travis Mayweather a posting aboard his vessel following the decommissioning of Mayweather's previous ship, the NX class Enterprise. Preferring to continue serving with Captain Jonathan Archer, his commanding officer from Enterprise, Mayweather did not give Stillwell an immediate answer as he first wanted to see what Captain Archer was going to do next.
