Donald Gregory Chin (October 7, 1955 – July 23, 2015) was an American activist and community leader who founded and operated the International District Emergency Center (IDEC).

[3] Chin founded IDEC with childhood friend and photojournalist Dean Wong in 1968, due to slow response times by Seattle police and fire services to emergency calls in the Chinatown-International District (CID).

IDEC provided a community-led solution to slow emergency response times in Seattle's Chinatown-International District (CID), a historically under-served diverse neighborhood.

[10] Through IDEC, Chin provided security services and staffed first aid stations at community events, held emergency preparedness trainings, and led a team of volunteer first responders in the CID for decades.

He started this when he was a kid, so he was only a little older, a big brother figure.”[4] Maiko Winkler-Chin, executive director of the Seattle Chinatown International-District Preservation and Development Authority (SCIDpda) reflected, "He provided a much broader sense of public safety that was never just about policing.

[17] Tributes to Donnie Chin in the wake of his murder included a candlelight vigil in Hing Hay Park and a "crossed ladder" salute from the Seattle Fire Department.

The Seattle Police Department, Mayor Ed Murray, Governor Jay Inslee, and former King County Executive Ron Sims also issued public statements in tribute to Chin.
