Park Tower, formerly known as SGZ-Hochhaus, is a high-rise building in the Westend-Süd district of Frankfurt, Germany. It was built in 1972 as the administrative headquarters of the Südwestdeutschen Genossenschafts-Zentralbank (since 2001 DZ Bank). The then 96-metre high building with a black and silver facade was briefly the tallest skyscraper in Frankfurt.
