Friends Without A Border (Friends) is a nonprofit, nongovernmental organization that funds medical treatment and healthcare programs serving disadvantaged children and their families in Southeast Asia. Founded in 1996 by photographer Kenro Izu, Friends provides direct financial and program support to Angkor Hospital for Children in Siem Reap, Cambodia, Lao Friends Hospital for Children in Luang Prabang, Laos, and The Lake Clinic in Siem Reap, Cambodia.

The international headquarters are located in New York, US, with one sister organization in Tokyo, Japan.

The organization was founded by noted fine art photographer Kenro Izu in 1996. Izu's visit to Cambodia to photograph the temples of Angkor inspired the pediatric hospital that would become Angkor Hospital for Children (AHC). During his first visit to Cambodia in 1993 and throughout subsequent trips, he was forever changed by his encounters with ill, malnourished, and disfigured children in desperate need of medical care. Izu made a commitment to build a pediatric hospital in Siem Reap and established Friends Without A Border for that purpose.

In 1996, the land for AHC was granted by the Governor of Siem Reap Province, Mr. Tong Chai. One year later, Friends Without A Border and the Cambodian Ministry of Health signed a 10-year agreement for AHC and broke ground on the hospital's future site. AHC opened its doors on February 22, 1999. In 2000, the Emergency Room and Dental Department opened, and that same year marked the start of the Orphanage Medical Assistance and Kardiac Kids programs. A year later, the HIV/Homecare program, Acute Care Unit, and Safety and First-Aid Training program for non-medical persons in Siem Reap began.

In 2002, Friends launched the Capacity Building and Health Education Program (CBHEP), a health promotion program that trains volunteer healthcare workers to improve health and hygiene at the village level. Also in 2002, the Eye Care Service Department and the Low Acuity Unit opened at AHC.

In 2005, the Oral Rehydration Therapy Corner opened. In 2006, the Acute Care Unit was upgraded to an Intensive Care Unit and the Physiotherapy Program was launched. Former U.S. President Bill Clinton toured AHC in December 2006.

The AHC Satellite opened at Sotnikum District Hospital in February 2010 to replicate the successful model of "treatment + education + prevention" in partnership with the provincial health department.

In January 2013, Friends and AHC celebrated the transition of management and operations to the dedicated hospital staff. The independence of AHC accomplished one of the original goals that was set in the beginning of a self-sustained hospital. Friends continues to be a presence at AHC and helps with their fundraising efforts.
