Dănești (Hungarian: Csíkdánfalva or colloquially Dánfalva, Hungarian pronunciation: [ˈtʃiːkdaːnfɒlvɒ]) is a commune in Harghita County, Romania. It lies in the Székely Land, an ethno-cultural region in eastern Transylvania. The commune is composed of a single village, Dănești. It also included Mădăraș until 2002, when it was split off to form a separate commune.

It was first recorded in 1567 as Danffalwa and in 1576 as Dánfalva. Its name derives from the Hungarian and means 'Daniel's village' using the archaic Hungarian form of the name. Until 1919, its Romanian name used to be Danfalău, which was then Romanianized to the current official name.

Until 1779, villagers were engaged in the operation of iron hammers, but in the 19th century it became a potters' village. Today, it has a black pottery factory. From 1762 to 1851, the village provided servicemen for the 7th Company of 1st Székely Infantry Regiment, guarding the Transylvanian Military Frontier. Wood processing, animal-breeding and transportation were the main preoccupation of the villagers.

The village administratively belonged to Csíkszék district in the Kingdom of Hungary until the administrative reform of Transylvania in 1876, when it fell within Csík County. In the aftermath of World War I and the Hungarian–Romanian War of 1918–1919, the village passed under Romanian administration; after the Treaty of Trianon of 1920, like the rest of Transylvania, it became part of the Kingdom of Romania. During the interwar period it fell within Plasa Centrală of Ciuc County. In 1940, the Second Vienna Award granted Northern Transylvania to Hungary and the village was held by Hungary until 1944. After Soviet occupation, the Romanian administration returned and the village became officially part of Romania in March 1945. Between 1952 and 1960, Dănești belonged to the Ciuc raion of Magyar Autonomous Region, and between 1960 and 1968 to the Mureș-Magyar Autonomous Region. In 1968, the region was abolished, and since then, the commune has been part of Harghita County.

The commune lies at the foot of the Harghita Mountains, on the banks of the Olt River, where the Köd Brook flows into the Olt. It is located in the central part of Harghita County, 21 km (13 mi) north of the county seat, Miercurea Ciuc, and is traversed by national road DN12 [ro] (part of European route E578). The Dănești train station serves the CFR Line 400, which runs from Brașov to Satu Mare.

Some of the natural resources found here are iron ore, mercury, kaolin, cinnabar, and mineral water.

At the 2011 census, the commune had a population of 2,292; out of them, 99% were Hungarians, 0.6% were Romanians, and 0.3% were Roma. At the 2021 census, Dănești had 2,079 inhabitants; of those, 96.63% were Hungarians.
