- In Polynesian mythology (specifically: Hawaii), Kapo is a goddess of fertility, sorcery and dark powers who can assume any shape she wills. She is the mother of Laka, although some versions have them as the same goddess. Her parents are Haumea and Kane Milohai. Kapo also had a detachable vagina, which she once used as a decoy to aid her sister Pele to flee the overzealous Kamapua'a.
- Kapo also stands for Kameradenpolizei, and refers to individuals who have been recruited by an enemy to police their own people. The term was used to describe concentration camp prisoners who were appointed to supervise other prisoners. They received more privileges than normal prisoners and were often brutal to the other prisoners.
- In Estonia KAPO stands for Kaitsepolitsei (Defense police) which protects the Estonian constitutional regime and performs counterintelligence in Estonia. Its tasks also include the prevention and discovery of crimes against the parliamentary democracy in Estonia. It's equivalents are the FBI in the United States, MI5 in the United Kingdom and FSB in the Russian Federation. The KAPO was established on April 12, 1920 by the Estonian Government. From 1925 to 1940 the institution was known as Poliitiline politsei (Political police).
