Trianon is a 45-storey, {{convert|186|m|ft|abbr=on}} skyscraper in the Westend-Süd district of Frankfurt, Germany, completed in 1993. For several decades until 2024, it served as the headquarters for DekaBank; other tenants are Deutsche Bundesbank (since 2015) and Franklin Templeton.Tom Sims and Matthias Inverardi (25 June 2024), [https://www.reuters.com/markets/europe/frankfurt-skyscraper-owner-files-insolvency-property-crisis-grips-2024-06-25/ Frankfurt skyscraper owner files for insolvency as property crisis grips] Reuters. Atop the building is an inverted pyramid suspended from the three corners. As of 2023, the tower is the eighth-tallest skyscraper in Frankfurt and also in Germany.

The Trianon's layout is roughly the shape of an equilateral triangle, the corners of which are formed by three-sided towers. The end is an inverted three-sided pyramid on the roof. It is the first structure in Germany to use high-strength concrete.
