Z Apodis (Z Aps) is a variable star in the constellation of Apus. It has an apparent visual magnitude which varies between 10.8 and 12.8, over a period of 39.37 days. Although described in the General Catalogue of Variable Stars as a cataclysmic variable star, it appears that it is a pulsating variable star, and has been classed as an RV Tauri variable star, type RVa. Other sources classify it is a type II (W Virginis) Cepheid.

Edna B. Florence discovered the variability of Z Apodis by examining photographic plates. The discovery was announced by Henrietta Hill Swope in 1931. Examination of 20 plates taken in 1925 allowed the derivation of a period of 19.5 days, almost exactly half of the currently accepted period. However, observations outside of that time window seemed "...too scattered to give any other indication of a period.", so the star was initially classified as an irregular variable.
