克拉灵顿（英语：Clarington）是一个位于加拿大安大略省南部杜林区的自治区，座落安大略湖北岸，并是大多伦多地区及金马蹄地区的最东端城镇。据2011年加拿大人口普查所示，克拉灵顿自治区内有84548名居民，而此自治区亦是奥沙华都会区的一部分。

安大略省政府于1973年改革此带地域的地方政府，原有的宝文围镇（Bowmanville）、克拉克乡（Clarke Township）和达灵顿乡（Darlington Township）于1974年合并成新的纽卡素镇（Town of Newcastle），名称来自克拉克乡内的纽卡素社区。有见该名称容易造成混淆，纽卡素镇于1994年正式更名为克拉灵顿自治区，名称由旧有的克拉克乡（Clarke）和达灵顿乡（Darlington）合并而成。

Clarington (2011 population 84,548) is a municipality in Ontario, Canada in the Regional Municipality of Durham. It was created in 1973 with the merging of the Town of Bowmanville, and the townships of Clarke and Darlington. It took its present name in 1994 after having been known as the Town of Newcastle from 1974-93. The name change was made to alleviate long-standing confusion between the municipality as a whole and the included village of the same name. Bowmanville is the largest community in the municipality and is the home of the municipal offices. The name "Clarington" is a combination of the names of the two historical townships, Clarke and Darlington, that made up the majority of the geographic area.
