A secosteroid () is a type of steroid with a "broken" ring. The word secosteroid derives from the Latin verb secare meaning "to cut", and 'steroid'. Secosteroids are described as a subclass of steroids under the IUPAC nomenclature. Some sources instead describe them as compounds derived from steroids.
