NKR

NKR is an acronym that can refer to several distinct entities. Two of the most commonly encountered are the Nagorno-Karabakh Republic and the National Kidney Registry.

Nagorno-Karabakh Republic (NKR) refers to a de facto state in the South Caucasus that proclaimed independence from Azerbaijan in 1991. It was governed by Armenian authorities with its capital in Stepanakert and maintained its own institutions, security forces, and borders, though it was not recognized by the United Nations or most countries. The status of the region has been the subject of prolonged conflict and negotiations. The 2020 war led to Azerbaijan regaining control of large portions of the territory, and since then the NKR's institutions have operated under the framework of the surrounding Azerbaijani-administered area, with continued reliance on regional actors and international diplomacy for governance and self-identification. The term NKR remains in geopolitical and historical contexts and is used primarily by sources focusing on the conflict’s history.

National Kidney Registry (NKR) is a United States-based nonprofit organization that coordinates living-donor kidney exchanges across multiple transplant centers. It uses paired donor exchanges and donor chains to expand the pool of compatible matches, re-linking donors and recipients so that more patients can receive transplants. The registry collects data from participating centers, matches donors to recipients, and organizes transplant chains that can involve multiple patients. Its work aims to improve transplant access, decrease wait times, and optimize outcomes for kidney patients.

Disambiguation: because NKR can refer to different topics, the intended meaning is usually clear from context, such as the subject, geographic region, or field of discussion.
