The Time and Temperature Building, originally known as the Chapman Building, and officially 477 Congress Street, is a 14-story office building on Congress Street in downtown Portland, Maine. The building, which replaced Preble House (a successor to the mansion of Commodore Edward Preble), is named after a large three-sided four-element eggcrate display screen on the roof that flashes the local time and temperature. It was built in 1924 as a 12-story building, with Maine's first indoor shopping center on its ground floor. It sits across Preble Street from the 10-story Fidelity Trust Building. Until the 1970s, these buildings were Portland's only skyscrapers.

The building, one of Portland's tallest, is visible from miles away, including from Peaks Island across the harbor, and it has become a landmark to Portlanders who depend on it for the sign's time and temperature, but also mariners sailing into Portland harbor.
