The World Hypertension League (WHL) is an organization that was initially incorporated in Switzerland on January 4, 1984 with fifteen European national leagues as charter members. Presently, in 2007, the WHL has 85 global member leagues and 1 Supporting Member. Only one full (Regular) membership is allocated to a given country; however, an Associate membership is possible for other leagues or societies within the given country.

After an organization requests membership into the WHL, and if the applicant is dedicated to the goals of the World Hypertension League and represents the hypertension community in their area, they are asked to fill out an application form and return it, along with any other pertinent information regarding their League, to:

Dr. Arun Chockalingam
