The Haji Bektash Veli complex 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 of the Sufi saint Haji Bektash Veli. After his death, his mausoleum was built here.
Before the secularization of Turkey in 1925, the complex was home to the pir evi of Haji Bektash Veli, which served as the international headquarters of the Bektashi Order.
