This is a list of bosses found in the Psychonauts series. The boss enemy is generally far stronger than the opponents Raz has faced up to that point.

Bobby Zilch is up to debate if consider to be a boss fight, since he isn’t deal in any fighting way other than racing against him in Milla's Dance Party. But since it requires to beat him along with Clem Foote and Crystal Flowers Snagrash on reaching the goal first, perhaps the closest is a lower mid-boss along with the other two mentioned. Evil Augustus while you do not hurt him at all except in the final fight, he actually attacks Razputin in both the Water Course and the second round with the Butcher so that gives him enough reasons to mark him as a boss.

- Judge (Mini-Boss) - Fought in Compton's Cookoff.
- Gluttonous Goats - Fought in Compton’s Cookoff.
- Panic Attack (Mini-Boss) - Fought in PSI King's Sensorium.
- Nightmare Maligula (Mini-Boss)- Fought in PSI King’s Sensorium.
- Die-Brarian - Fought in Cassie's Collection.
- Bad Mood (Mini Boss) - Fought in Bob's Bottles.
- Truheltia Memonstria - Fought in Bob’s Bottles.
- Maligula - Fought in the Deluge Of Grulovia (Lucrecia's Lament).
The Judge, Panic Attack and Bad Mood are all recurring enemies that are marked onscreen as bosses the first time they appear, but they are no stronger in these introductory encounters than later, generic ones. While Heavy Censor can fall in the category of large enemies similar to in the first game, he features much more attacks and health than the average Stamping censor and besides in the hordes of enemies rarely appears more than one Heavy Censor, similar case to Mini-Bosses like Bad Mood.
