Harmony Day is celebrated annually on March 21st in Australia. Harmony Day began in 1999, coinciding with the United Nations International Day for the Elimination of Racial Discrimination. Each year, it is marked by people coming together and participating in local activities. The continuing message of Harmony Day is 'Everyone Belongs'. It is about community participation, inclusiveness, celebrating diversity, respect and belonging.

Communities themselves decide how they would like to come together to mark the occasion – some have morning teas, others organise a fair and some celebrate by dressing in national costumes. Since 1999, a wide variety of groups including sports organisations, community groups, local government, churches, schools and businesses have staged more than 55,000 Harmony Day events.

Orange is the colour chosen to represent Harmony Day.
