The Indonesian Ocean Policy (IOP) is a new milestone in managing its oceans since Indonesia ratified the UNCLOS 35 years ago. Indonesia underwent several paradigm shifts in strengthening ocean governance from 1957 to 2014. This research aims to analyse three paradigm shifts in strengthening ocean governance in Indonesia. The research revealed that the milestone of the first shift was the 1957 Djuanda Declaration, recognised by the UNCLOS in 1982, regarding the concept of an archipelago state, called the ‘ocean space paradigm.’ The second, which occurred in the Reformation period (1998-2014) was called the Ocean Development paradigm, while the third paradigm shift was after President Jokowi launched Indonesia’s vision as a Global Maritime Fulcrum. This third paradigm shift was also associated with the emergence of the IOP, which contributes to national development and pays comprehensive attention to the constellation of relations between the countries in Asia and various initiatives in the region.
