Kosovo Telecom, formerly known as Post and Telecommunications of Kosovo (commonly abbreviated as PTK; Albanian: Posta dhe Telekomi i Kosovës, Serbian: Пошта и телекомуникације Косова / Pošta i telekomunikacije Kosova) is the postal and telecommunications authority of Kosovo. It was created in 1959, originally under the name of The Post, Telephone and Telegraph of Kosovo.

On 29 June 2005, Post and Telecom of Kosovo was transformed into a Joint Stock Company, with the new name PTK J.S.C. The authority has three business units: Post of Kosovo, Telecom of Kosovo, and Vala , its mobile operator unit. The units are licensed by Telecommunication Regulation Authority of Kosovo.

Vala was the first licensed mobile operator in Kosovo. In operation since 2000, it is the largest mobile operator in Kosovo with approximately 1,150,000 customers.Monaco Telecom is responsible for management of the network and the network uses a Monaco mobile network code. An LTE network has been built by Vala, powered by Alcatel Lucent and Nokia Networks.

PTK stopped operating only during the Kosovo War. During the conflict, assets of the company were either stolen or destroyed, leading to interruptions of postal and telecommunication services. After the conflict, PTK launched Vala, the largest mobile operator in the country.
