Southern Star Amphitheatre was an amphitheatre located at AstroWorld in Houston, Texas. It opened in the southeast corner of the theme park in 1985. The venue was frequented by notable performers including The Beach Boys and Kansas. Prior to the Southern Star opening, concerts were held in the same area on a flat field with the stage at the east end. The Southern Star saw a decline in the number of top-billed acts when the Cynthia Woods Mitchell Pavilion opened in 1990. Reserved seating was available and a grassy lawn was provided to guests with general admission. The venue closed along with the theme park in 2005.
