The Alonzo King LINES Ballet (AKLB) is an American contemporary ballet company based in the San Francisco Bay Area. The ballet company, founded by choreographer Alonzo King, premiered at San Francisco State University's McKenna Theatre in 1982.

Contemporary ballet is a genre of dance that incorporates elements of classical ballet and modern dance. It employs classical ballet technique and in many cases classical pointe technique as well, but allows a greater range of movement of the upper body and is not constrained to the rigorously defined body lines and forms found in traditional, classical ballet. Many of its attributes come from the ideas and innovations of 20th-century modern dance, including floor work and turn-in of the legs. The style also contains many movements emphasizing the body's flexibility.
