The Sultan Ibrahim Building is a former state secretariat building of Johor. It is located at Bukit Timbalan in Johor Bahru, Malaysia. The building was constructed between 1936 and 1939 and was completed in 1940 as the British colonial government attempted to streamline the state's administration. It was officially opened by the late Sultan Ibrahim of Johor.
It was also the tallest building in Malaya during the pre-Merdeka era. In Johor Bahru itself, it stood unchallenged as the tallest building in the town until the completion of the Merlin Tower in the 1970s.
The offices of the state secretariat have now moved to Kota Iskandar. There are plans to convert the building into a museum.
