Marvin's Marvelous Mechanical Museum is the debut studio album by American rock band Tally Hall, originally released on November 12, 2005. Their previous recordings were all independently produced and distributed demos. All of the tracks on the album are finished versions of their demo tracks, with the exception of "Haiku," which is a completely new song. The album gets its name from a museum of mechanized curiosities that is located in Farmington Hills, Michigan. The album's cover art is also based on a number of machines located within the museum.

Tally Hall is an American rock band formed in Ann Arbor, Michigan, in December 2002, and publicly active until the conclusion of their Good & Evil tour in 2011. The band is known for its upbeat melodies and whimsical lyrics. The members originally described their musical style as "wonky rock", later redefining their sound as "fabloo", in an effort to not let their music be defined by any particular genres after critics began defining the characteristics of "wonky rock".
