The North American Central Time Zone (CT) is a time zone in parts of Canada, the United States, Mexico, Central America, some Caribbean Islands, and part of the Eastern Pacific Ocean.

Central Standard Time (CST) is six hours behind Coordinated Universal Time (UTC). During summer most (but not all) of the zone uses daylight saving time (DST), and changes to Central Daylight Time (CDT) which is five hours behind UTC.

The province of Manitoba is the only province or territory in Canada that observes Central Time in all areas.

The following Canadian provinces and territories observe Central Time in the areas noted, while their other areas observe Eastern Time:

Also, most of the province of Saskatchewan is on Central Standard Time year-round, never adjusting for Daylight Saving Time. Major exceptions include Lloydminster, a city situated on the boundary between Alberta and Saskatchewan. The city charter stipulates that it shall observe Mountain Time and DST, putting the community on the same time as all of Alberta, including the major cities of Calgary and Edmonton. As a result, during the summer, clocks in the entire province match those in Alberta, but during the winter, clocks in most of the province match those in Manitoba.

Nine states are contained entirely in the Central Time Zone:

Seven states are split between the Central Time Zone and the Mountain Time Zone:
