Fulton Center is a subway and retail complex centered at the intersection of Fulton Street and Broadway in Lower Manhattan, New York City. The complex was built as part of a $1.4 billion project by the Metropolitan Transportation Authority (MTA), a public agency of the state of New York, to rehabilitate the New York City Subway's Fulton Street station. The work involved constructing new underground passageways and access points into the complex, renovating the constituent stations, and erecting a large station building that doubles as a part of the Westfield World Trade Center mall.

The project, first announced in 2002, was intended to improve access to and connections among the New York City Subway services stopping at the Fulton Street station. Funding for the construction project, which began in 2005, dried up for several years, with no final approved plan and no schedule for completion. Plans for the transit center were revived by the American Recovery and Reinvestment Act of 2009. The project used to be referred to as the Fulton Street Transit Center, but was re-branded the Fulton Center in May 2012 because of a heightened emphasis on retail. The complex officially opened on November 10, 2014, along with the adjacent Dey Street Passageway.

Through the Dey Street Passageway, the complex connects to the World Trade Center, the Westfield World Trade Center mall, PATH station, and observation deck, and provides connections to the Chambers Street–World Trade Center/Park Place/Cortlandt Street (2, ​3​, A, ​C, ​E​, ​N, ​R, and ​W) and WTC Cortlandt (1) stations, as well as the PATH's World Trade Center station. Westfield Corporation operates the retail space as an extension of the Westfield World Trade Center, a block to the west.
