In 1973, the City of Orange sought ideas to commemorate its centennial anniversary. Inspired by the Orange Street Fair of 1910, the City introduced the Orange International Street Fair (OISF) as part of its one-hundred-year celebration. The event was an immediate success and has since grown into a beloved annual tradition held each Labor Day weekend in and around Plaza Park within the historic Old Towne Orange district.

In 1985, the City of Orange formally transferred ownership and production of the Orange International Street Fair to Orange International Street Fair, Inc. (OISF, Inc.), establishing the organization as the event’s steward and ensuring its continued growth as a community-driven tradition.

In 2025, OISF, Inc. further expanded its role within the community by assuming production and financial responsibility for two additional long-standing City of Orange traditions: the annual Treats in the Streets celebration and the Tree Lighting Ceremony and Candlelight Choir Procession. This transition ensured the continuation and enhancement of these cherished events while preserving their community-focused spirit and historic significance.

Orange International Street Fair, Inc. (OISF, Inc.) is a 501(c)(4) certified non-profit organization comprised entirely of volunteer board and committee members. While OISF, Inc. continues to partner with the City of Orange for essential municipal support services, the organization is solely responsible for the planning, management, and financial oversight of the Orange International Street Fair, Treats in the Streets, and Tree Lighting Ceremony.
