An audition website aggregates acting, modeling, and dancing auditions online. One of the most significant organizations for professional screen and theater casting in the United States is the Casting Society of America (CSA).

Traditionally, only talent agents would be able to schedule auditions for actors, models, dancers, and other performers, but with the invention of audition websites, public as well as private auditions are now available online to everyone who might be interested.

Audition websites have become an integral component of the employment statistics^[1] of actors and other entertainment industry professionals. Most acting assignments are typically short-term, ranging from a day to a few months.

Some audition websites require membership, while others are free to use. Most auditions require the members to regularly browse through audition listings and sign up for, or even self-tape and submit their auditions through the website, which enables members to pick and choose the types of jobs they audition for.

Except for a membership fee, audition websites typically don't charge anything for their use, and unlike talent agents, they also don't receive a percentage of the income earned from jobs booked through their service. This has caused these services to become very popular, and some of them have millions of members.

A casting director, talent agent, film producer, or movie director can use audition websites to cast talent for commercials, music videos, movies, and other entertainment projects.
