Kuju Ltd is an international video game developer. Kuju was formed in 1998 in Shalford, Surrey, England, after a management buyout of Simis from Eidos Interactive. Kuju has released titles across different devices, ranging from Art Academy on the Nintendo DS, The Lord of the Rings: Aragorn's Quest for the Wii, and an Xbox One title, Powerstar Golf.

The name "Kuju" originates from the initials of the founders’ first names: Ian Baverstock and Jonathan Newth. Jonathan was leafing through a Japanese dictionary when he found the numbers nine and ten – "ku" and "ju" – corresponding to the positions of "I" and "J" in the English alphabet. The combined result was Kuju.
