Kosrae Self Government Day is a significant holiday celebrated on the island of Kosrae in the Federation of Micronesia. Also known as 'Kosrae Constitution Day,' this national holiday is observed on the 11th of July every year. The day marks the commemoration of Kosrae's move to self-government, which transpired in 1984, epitomizing autonomy and a milestone shift away from a greater, 'flag-free' Micronesia. This is a public holiday in Kosrae, meaning most businesses, schools, and offices are closed.

The day is marked by a range of cultural festivities and lively celebrations providing a vibrant display of Kosraean culture and tradition. Cultural performances, traditional games, and music concerts are prevalent. There are also sports competitions and an array of food stalls showcasing local cuisine. These social gatherings serve as a celebration of the resilience of the Kosraean people and reflect on the growth and progress that they have made since attaining self-governance.

Kosrae Self Government Day is an integral part of Kosrae's cultural identity and is more than just a day off work. It serves as a reminder to the people of the island—and to the rest of the world—of their capability to self-govern and maintain their unique heritage. The day serves to remind the residents of their political transformation and the strides forward they have taken as a society. This day is a demonstration of Kosrae's pride and sworn commitment to sustain their heritage and values in the face of external influences.
