The name "Pine Brook Stadium" was the name originally given to the track by builder Dick Marlow. But at some point during the promotional reign of Jack Dowie, the name was changed to "Pine Brook Speedway." Later, when Jack Bellinato was in charge, he experimented with "Home of Champions Speedway" but it never stuck. Everyone called it "Pine Brook," be it Stadium or Speedway.
Many people thought of Pine Brook as one word, Pinebrook. But it is two words, named after the Pine Brook section of Montville Township, in which the track was located.
