The Haji Bektash Veli complex (Turkish: Hacıbektaş Külliyesi) is an Alevi Islamic Cultural Monument of the Republic of Turkey, located in Hacıbektaş, Nevşehir province.

It was built in the 13th century as a teqe (dergâh) of the Sufi saint Haji Bektash Veli.

Before the secularization of Turkey in 1925, the complex was home to the pir evi ("pir's house") of Haji Bektash Veli, which served as the international headquarters of the Bektashi Order.

Nowadays, the Haji Bektash Veli Complex is visited by hundreds of thousands of Alevis, Bektashis, and even Sunni Muslims from Turkey, Albania, and the Turkish diaspora in Europe and around the world.

Since 2012, the Haji Bektash Veli complex is on the World Heritage Sites Tentative list of the UNESCO.
