Brad Boimler

Bradward "Brad" Boimler () is a fictionalcharacter from the American science fictiontelevision seriesStar Trek: Lower Decks. He is known for being ambitious while diligently following the rules of the service, and pleading excessively for his best friend, Ensign Beckett Mariner, an openly insubordinate ensign who regularly skirts the consequences, to do the same—although in the far future, Boimler is remembered for the Boimler Effect, a ship-wide mandate aboard the USS Cerritos encouraging breaking the rules, a distinction Boimler would not approve of. However, as the series progresses, Boimler eventually distinguishes himself as a courageous and resourceful officer of considerable command potential.

Boimler is voiced by Jack Quaid, who also reprises the role in a live-action crossover in "Those Old Scientists", an episode of the 2023 second season of Star Trek: Strange New Worlds.
