The Messeturm, or Trade Fair Tower, is a 63-storey, 257 m (843 ft)[5] skyscraper in the Westend-Süd district of Frankfurt, Germany.

It was the tallest building in Europe from its completion in 1990 until 1997 when it was surpassed by the Commerzbank Tower, which is also located in Frankfurt.

It is one of the few buildings in Germany with their own postal code (60308), the others being Opernturm, another Frankfurt skyscraper, and the summit station on Zugspitze.

When Germany submitted its application to have Frankfurt selected as the seat of the European Union's Anti-money-laundering authority (AMLA) in 2023, the Messeturm was one of three options – alongside Tower 185 – presented as potential location for the new agency.

The construction of the building's foundation set a world record for the longest continuous concrete pour.
