This article is about the demographic features of the population of Swaziland, including population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects of the population.

The majority of Swaziland's population is ethnic Swazi, mixed with a small number of Zulus and white Africans, mostly whites of British and Afrikaner descent. This population also includes a small segment within it that is mixed with any number of these ancestries.

Traditionally Swazis have been subsistence farmers and herders, but most now work in the growing urban formal economy and in government. Some Swazis work in the mines in South Africa. Swaziland also received Portuguese settlers and black refugees from Mozambique. Christianity in Swaziland is sometimes mixed with traditional beliefs and practices. Most Swazis ascribe a special spiritual role to the Swazi Royal Family.

The country's official languages are Siswati (a language related to Zulu) and English. Government and commercial business is conducted mainly in English. Asians, Afrikaners, Portuguese, and black Mozambicans speak their own languages.
