Leaving Wonderland... in a Fit of Rage is the fourth studio album by American alternative rock band Marcy Playground, released on July 7, 2009[2] by WOZ Records.

[11][12] Leaving Wonderland... in a Fit of Rage was recorded in part with original band member Dylan Keefe.

"[19] The Toronto Sun considered the album to be "a fairly enjoyable and varied set of mellow Beatle-pop and roots, peppered with surprisingly crunchy guitar-rockers.

"[15] The Intelligencer Journal concluded that "all 12 songs on Leaving Wonderland ... are excellent, driven by Wozniak's gift for melody.

"[20] AllMusic wrote that "it deserves to be heard by a wider audience as it proves that there's more to Marcy Playground and Wozniak than one grunge-era hit.
