The Majesty Building is an incomplete 18-story office building in Altamonte Springs, Florida. The 300,000-square-foot (27,871 m2) structure is being constructed by the religious broadcaster Associated Christian Television System, owner of the SuperChannel 55 television station. If completed, it would be the tallest building in Seminole County.

Construction of the building began in May 2001 with a planned completion date of February 2003. However, due to funding issues and the owner's desire to avoid debt financing, the building was never fully completed. Construction has continued sporadically, but as of November 2024 there is no planned completion date.

Due to its proximity to Interstate 4 and towering appearance, the building is widely known as the I-4 Eyesore or Eyesore on I-4.
