Taipei 101 is a landmark skyscraper located in Xinyi District, Taipei, Taiwan. The building, designed by C.Y. Lee & Partners and constructed primarily by KTRT Joint Venture and Samsung Engineering & Construction is the world’s tallest completed skyscraper according to the Council on Tall Buildings and Urban Habitat, the arbiter of tall building height. Taipei 101 received the Emporis Skyscraper Award in 2004. It has been hailed as one of the Seven New Wonders of the World (Newsweek magazine, 2006) and Seven Wonders of Engineering.

The building contains 101 floors above ground and 5 floors underground. Its postmodern style combines Asian and international modern and traditional elements. It is designed to withstand typhoons and earthquakes. A multi-level shopping mall adjoining the tower houses hundreds of fashionable stores, restaurants and clubs. Fireworks launched from Taipei 101 feature prominently in international New Year’s Eve broadcasts, and the tower appears frequently in films, television shows, print publications, anime media, games, and other elements of popular culture.

The name of the tower reflects its floor count. The number is pronounced in English simply as One Oh One and in Mandarin and other local languages by the equivalent.

Taipei 101 is owned by the Taipei Financial Center Corporation and managed by the International division of Urban Retail Properties Corporation based in Chicago. The name originally planned for the building, Taipei World Financial Center, was derived from the name of the owner. The original name in Chinese was literally, Taipei International Financial Center.
