Janke is a name of Germanic origin.
This name is popular in countries speaking Dutch or Afrikaans, such as The Netherlands and South Africa. As a first name, it is usually attributed to a woman in South Africa. (This being due to a TV series aired in the 1990s where one of the main female protagonists was named Janke). It may also appear as a male first name amongst other families with ties to Germanic background. Spelling variations include Jancke, Jankhe, and (rarely) Janckhe. The name is derived from the Dutch male name Jan (a form of John or Johan), and features the suffix "-ke", which makes it a pet name, almost meaning "Baby Jan".
