Kediri or Kadiri (also known as Panjalu) is a Hindu Javanese Kingdom based in East Java from 1042 to around 1222.

Despite the lack of archaeological remains, the age of Kediri sees much development in classical literature.

Mpu Sedah's Kakawin Bharatayuddha, Mpu Panuluh's Gatotkacasraya, and Mpu Dharmaja's Smaradhana blossom in this era.

The kingdom's capital is believed to have been established in the western part of the Brantas River valley, somewhere near modern Kediri city and surrounding Kediri Regency.

Other than Kadiri, its capital is also often referred to as Daha or Dahana.
