宗（宗喀语：རྫོ་ཁག།，拉丁字母转写：Dzongkhag）是不丹的二级地方行政机构（相当于县）。宗由几个更小的行政区——格窝（相当于“乡镇”）组成，并归属于区管辖。

宗的行政长官称为宗达，宗达由国王直接任命，经过不丹国民议会批准履任。

宗达分别向地区行署专员和内政部负责，掌管本宗范围内的教育、农业、畜牧业、医疗卫生、工商贸易、道路和交通运输、市政建设等行政事务。

A dzongkhag (*****: རྫོང་ཁག, Wylie: rdzong khag, Dzongkha dzongkhak) is an administrative and judicial district of Bhutan. The twenty dzongkhags of Bhutan are further divided into 205 gewogs. Some larger dzongkhags have one or more of an intermediate judicial division, known as dungkhags (sub-districts), which themselves comprise two or more gewogs. The Parliament of Bhutan passed legislation in 2002 and 2007 on the status, structure, and leadership of local governments, including dzongkhags. Its most recent legislation regarding dzongkhags is the Local Government Act of 2009.
