Hatzalah (/hətˈsʌlə/; Hebrew: הַצָּלָה, lit. 'rescue, relief') is one of several Jewish volunteer emergency medical service (EMS) organizations serving mostly areas with Jewish communities around the world, giving free medical service no matter their religion. Most local branches operate independently of each other, but use the common name. The Hebrew spelling of the name is always the same, but there are many variations in transliteration, such as Hatzolah, Hatzoloh, and Hatzola. It is also often called Chevra Hatzalah, which loosely translates as "Company of Rescuers", "Group of Rescuers", or "Rescue Squad". It is the largest volunteer medical group in the United States.
