Acrux
Acrux is the brightest star in constellation Crux (the Southern Cross) and the thirteenth brightest star in the nighttime sky, at visual magnitude 0.77. Acrux is represented in the flag of Australia as one of the 5 stars that comprise the Southern Cross. Since Acrux is at roughly −60° declination, it is generally only visible south of the Tropic of Cancer and therefore didn't receive an ancient traditional name; "Acrux" is simply a combination of the A in Alpha plus Crux (meaning "cross"). Acrux is the southernmost first magnitude star, just a bit more southerly than Alpha Centauri. Acrux can be seen as far north as Miami, Florida, but it only barely rises above the horizon. You might be able to see it due south around May 8 (any year) at about 9:00 pm. If you wait a around until midnight, Alpha Centauri and Hadar will also be visible around that date as well (also directly to the south and just over the horizon).
