Daye (Chinese: 大冶; pinyin: Dàyě) is a county-level city in eastern Hubei province, China. It is under the administration of the Huangshi prefecture-level city.

Before the adoption of the Hanyu Pinyin, the name of the city was often transcribed in English as Tayeh.

As it is usually the case with county-level cities, Daye includes both an urban core and a fair amount of rural land in all directions, with smaller townships (zhen) such as Dajipu (大箕铺). According to the Fifth Population Census of China (2000), the entire county-level city of Daye had 813,600 residents, with a population density of 558 people per square kilometer.

The Daye Lake south of Daye's urban core is surrounded by parks and fishing ponds, and is a popular place for recreation.

For a traveler who goes on G316 from Wuhan toward the south-east, Daye appears as a border between the more urban and more rural parts of the province. Daye sits on the south-eastern border of the heavily industrialized Wuhan/Ezhou/Huangshi metropolitan area; south of it, the much more rural Yangxin County begins.

Daye is an industrial city, a center of mining and metallurgy, both ferrous and non-ferrous; its name means 'developing a prosperous smelting industry' (大兴炉冶).

Copper mining and smelting was conducted at Daye's Tonglüshan Mine (, 30°04′52″N 114°56′07″E / 30.08111°N 114.93528°E / 30.08111; 114.93528) as early as the Spring and Autumn period (6th century B.C.E.), if not earlier. Tonglüshan Mine is located just southwest of the modern city, and now has a museum.
