The International Lesbian Information Service (ILIS) was international organization with the purpose to foster international lesbian organizing. It was started within ILGA in 1980. Next year, at a separate lesbian conference arranged prior to the ILGA Turin conference, lesbian organizations decided that ILIS should be a separate organization.
ILIS arranged several international conferences. The activities seem to have gradually stopped in the late 1990s.
ILIS also published a newsletter. The publishing duties and the location of the ILIS Secretariat rotated as follows:
