Indolizine is an heterocyclic compound with the formula C₈H₇N). It is an uncommon isomer of indole with the nitrogen located at a ring fusion position. The saturated analog is indolizidine, which is the core of a variety of alkaloids such as swainsonine.^[3]

Examples of some simple fully synthetic substituted indolizines include 2ZEDMA, 1ZP2MA, and 1Z2MAP1O.^[4]^[5]
