Post and Telecom of Kosovo (commonly abbreviated as PTK; Albanian: Posta dhe Telekomi i Kosovës) is the postal and telecommunications authority of Kosovo.

The company was founded in 1959, originally under the name of The Post, Telephone and Telegraph of Kosovo, and adopted its current name on 12 September 1990.

During the conflict, assets of the company were either stolen or destroyed, leading to interruptions of postal and telecommunication services.

[2] After the conflict, PTK launched Vala, the largest mobile operator in the country, with the assistance of Monaco Telecom.

On 29 June 2005, Post and Telecom of Kosovo was transformed into a joint stock company, with the new name PTK J.S.C.
