9 DeKalb Avenue, alternatively referred to as 340 Flatbush Avenue Extension, is a supertall residential skyscraper under construction for Brooklyn, New York being developed by Michael Stern's JDS Development Group and Joseph Chetrit's Chetrit Group. When completed it will become the tallest structure in New York City outside Manhattan, as well as the first supertall building in Brooklyn.

9 DeKalb will incorporate the historical Dime Savings Bank building, which JDS and Chetrit finished acquiring in late 2015. The Dime Savings Bank building was previously owned by J.P. Morgan Chase and was used as a bank branch. The building was sold for $90 million, and was first placed on the market in late 2014. Originally, developers planned to acquire the building occupied by Junior's, a cheesecake restaurant, to use its air-rights. However, Alan Rosen, the owner, turned down a $45 million buyout, as well as a later deal for less that would have included retail space in the new building.

Plans for the structure were first filed in mid-2014, calling for a seventy story, 775 foot building, also designed by SHoP Architects. The building will mark the third collaboration between JDS and SHoP, after 111 West 57th Street and American Copper Buildings.

In early 2016, new plans were released with a slight height extension and reduced space for retail. Proposed modifications to the existing Dime Savings Bank structure were approved by New York City Council's Landmarks Preservation Commission in April 2016, indicating support for the building's construction. Changes include the removal of non-original additions to the structure and repairing damage to the building's marble and copper.

The proposed structure will be located in Downtown Brooklyn and will be several blocks away from the former tallest buildings in Brooklyn, Avalon Willoughby West and 388 Bridge Street (they were surpassed by The Hub in 2017). If built as planned, the building will be slightly under twice the height of Avalon and 388 Bridge.
