Benjamin William Mkapa Pension Tower, Office tower in Dar es Salaam, Tanzania.

The Benjamin William Mkapa Pension Tower is a 21-story high-rise situated on Azikiwe Street in Dar es Salaam. It houses retail spaces and commercial offices dedicated to pension administration and related services.

Construction began under the Tanzania Petroleum Development Corporation and the National Housing Corporation, but lack of funds halted work for five years. In late 2004 the National Social Security Fund bought the unfinished building and resumed construction. It now bears the name of Benjamin William Mkapa.

The building's former name, Mafuta House, comes from the Swahili word mafuta, meaning oil, a reference to its original owners, the Tanzania Petroleum Development Corporation. The current name honours Benjamin William Mkapa, Tanzania's third president, whose pension fund, the NSSF, financed the tower's completion.

The structure sits in the Kivukoni district, making it accessible in the city center. Since it functions as a commercial property, visitors should check access rules and hours for retail and office areas.

The building was begun by the Tanzania Petroleum Development Corporation and the National Housing Corporation, then stood unfinished for five years when their funds ran out. The National Social Security Fund bought the shell in late 2004 and resumed work, which is how a stalled oil-company project became a pension fund tower.
