The Anziku Kingdom, also called the Teke Kingdom, the Tyo Kingdom or Tio Kingdom, was a pre-colonial West Central African state of modern Republic of Congo.

The word Anziku comes from the KiKongo phrase "Anziku Nziku" meaning "to run" referring to inhabitants who leave the interior to protect the border. The term was applied most famously to the Bateke, which is why the state is sometimes called the kingdom of Teke or Tiyo. Other groups within the Anziku included the Bampunu and Banzabi.

In the early 17th century, the Anziku population controlled the copper mines around Kongo's northeast border and may have been there specifically as a buffer. When the Anziku groups consolidated to form their own independent kingdom, Kongo proceeded to take over the mines personally. This process was complete by the 1620s. There was, however, fighting between the two states over the region throughout the 17th century.
