The Kuala Lumpur International Book Fair (KLIBF), or Pesta Buku Antarabangsa Kuala Lumpur (PBAKL), is a major annual literary event in Malaysia, recognized as the largest book fair in Malaysia and one of the largest in Southeast Asia. It is truly an annual major event in the global publishing calendar.

Since 1991, the KLIBF venue has always been the World Trade Centre Kuala Lumpur (WTCKL), located at 41 Jalan Tun Ismail, Chow Kit, Kuala Lumpur, except for the 2016 edition that was held at the Malaysia Agro Exposition Park Serdang (MAEPS).
