The Altona Observatory () was an astronomical observatory situated in the Palmaille, in Altona, Hamburg. The observatory was founded by Heinrich Christian Schumacher in 1823 and continued to operate until 1871, 21 years after his death. It closed due to funding being cut off following the cession of the 'Elbe Duchies' of Schleswig, Holstein, and Saxe-Lauenburg by Denmark to Austria and Prussia following the Second Schleswig War.
