Demographics of the population of Belize include population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects.

Belize is the most sparsely populated nation in Central America. It is larger than El Salvador. Slightly more than half of the people live in rural areas. About one-fourth live in Belize City, the principal port, commercial centre, and former capital. About 80% of the population are Christian.

Most Belizeans are of multiracial descent. About 52.9% of the population is of mixed Indigenous (mostly Maya) and European descent (or Mestizo), 24.9% are Kriols, about 10.6% are Maya, and about 6.1% are Afro-Amerindian (Garifuna). The remaining population includes European, East Indian, Chinese, Middle Eastern, and North American groups. In the case of Europeans, most are descendants of Spanish and British colonial settlers, whether pure-blooded or mixed with each other. Most Spanish left the nation just after it was taken by the British colonists who, in the same way, left after independence. Dutch and Prussian Mennonites settled in Belize, mostly in isolated areas.

According to the Statistical Institute of Belize, the current population stands at 441,471.

In conjunction with a census of the British Empire, census data was compiled for Belize in 1790, 1816, 1823, 1826, 1829, 1832, 1835, 1861, 1871, 1881, 1891, 1901, 1911, 1921, 1931 and 1946. Belize conducted its own censuses in 1960, 1970, 1980, 1991, 2000, 2010, and 2022.
