Sickology 101 is the eighth studio album, and the second in the "Collabos" series, by rapper Tech N9ne.

The album features guest appearances from Krayzie Bone, Crooked I, Chino XL, Messy Marv, Ron Ron, Potluck, also featured are fellow Kansas City rappers Cash Image, D-Locc Da Chop and the 57th Street Rogue Dog Villians [sic]. Furthermore, fellow Strange Music rappers Krizz Kaliko, Kutt Calhoun and Big Scoob are featured. It features production by producers that have previously collaborated with Tech, like Tramaine "Young Fyre" Winfrey, Jonah "Matic Lee" Appleby, Adam "Wyshmaster" Cherrington, and Michael "Seven" Summers, with additional production alongside Young Fyre, like Josh "Karbon" Brunstetter and Brian "Yung Fokus" Reid. The additional production credits were absent from the copies of the album in the initial pressing, but were added in subsequent pressings.
