The Theater Equation is a 2016 live album and DVD/BluRay by Arjen Anthony Lucassen's progressive rock/metal rock opera project Ayreon. The Theater Equation consists of a live performance, with cast, choir and small orchestra, of the 2004 album The Human Equation. It marks the first time an Ayreon album was played live entirely, and the first Ayreon live release.

A grand, theatrical live concert film capturing Ayreon's 30th Anniversary spectacle at the 013 in Tilburg, featuring a three-decade-spanning setlist of Ayreon favourites and deep cuts, an all-star cast of vocalists and musicians, elaborate stage design, cinematic visuals and special effects that transform the performance into an immersive sci‑fi musical experience.
