Ganirelix, sold under the brand names Orgalutran among others, is a medication used in assisted reproduction to prevent early ovulation. This can increase the number of suitable eggs available for in-vitro fertilisation. It is given by injection under the skin.

Common side effects include abdominal pain, headache, vaginal bleeding, nausea, and ovarian hyperstimulation syndrome. It should not be used in those with latex allergies. It should not be used once pregnancy has occurred. It is a gonadotropin-releasing hormone (GnRH) antagonist. It works by blocking receptors for GnRH, which decreases LH and therefore stops ovulation until this is desired.

Ganirelix was approved for medical use in the United States in 1999 and Europe in 2000. In the United States 5 doses of 0.25 mg costs about 380 USD as of 2021.
