V744 Centauri, is a semi-regular variable pulsating star in the constellation Centaurus. Located 3 degrees north north east of Epsilon Centauri, It ranges from apparent magnitude 5.1 to 6.7 over 90 days. It is unusual in that it is a red star with a high proper motion (greater than 50 milliarcseconds a year). When it is near its maximum brightness, it is visible to the naked eye under good observing conditions.
In 1964, Wolfgang Strohmeier et al. announced the discovery that the star is a variable star. It was given its variable star designation, V744 Centauri, in 1968.
