Census Division No. 23 (Churchill - Northern Manitoba) is a census division located within the Northern Region of the Province of Manitoba, Canada. Unlike in some other provinces, census divisions do not reflect the organization of local government in Manitoba.

The census division contains the Atlantic deep sea Port of Churchill.

The population of the census division was 8,252 in the 2006 census. The census division has a very diversified economic base ranging from mining, forestry, trapping, transportation and arctic resupply escorting.

In the 2021 Census of Population conducted by Statistics Canada, Division No. 23 had a population of 4,690 living in 1,529 of its 2,293 total private dwellings, a change of -47.7% from its 2016 population of 8,971.
