The National Weather Service Weather Forecast Office New Orleans/Baton Rouge, Louisiana is a National Weather Service office located in Slidell, Louisiana.

The National Weather Service Weather Forecast Office New Orleans/Baton Rouge has its origins in a U.S. Army Signal Service office opened in Downtown New Orleans on October 4, 1870. A hurricane forecast center operated in the New Orleans office from 1935 until 1966, when its responsibilities were transferred to the National Hurricane Center. In 1979, the New Orleans forecast office moved to Slidell, merging with the radar observatory that had operated there since 1972. In 1993, the Baton Rouge forecast office was closed and its functions were transferred to the office in Slidell. In November 2023, it was notified to the public that the radar would be moved someplace else as it would provide better coverage of any weather that needed to be monitored. From that point until March 2024 meteorologists has to rely off of radars at Lake Charles from the west and Mobile from the east. In March 2024, the new radar was stationed in Hammond and now provides coverage in between Lake Charles and Mobile.

The National Weather Service Weather Forecast Office New Orleans/Baton Rouge, Louisiana currently provides programming for 6 NOAA Weather Radio stations.
