Fleabass was a bass guitar brand founded in 2009 by Michael Balzary, better known as Flea, the bassist of the Red Hot Chili Peppers. The company's stated mission was to provide affordable, high-quality bass guitars aimed at young and beginner players, motivated by Flea's belief that a decent first instrument should not be out of reach for aspiring musicians.

The lineup centered on three models: the full 34-inch scale Touring Bass (also referred to as the Model 32), the short-scale 30-inch Junior Bass, and the entry-level Street Bass. Instruments were manufactured in China and finished in distinctive two-tone color schemes with names like Sunny Bass (yellow/orange), Water Bass (orange/blue), Punk Bass (pink/green), and The Wild One (white/black), giving the line a visually playful identity distinct from traditional bass designs.

Production was short-lived, with the brand winding down after a limited run of instruments. Fleabass guitars have since become collectible among fans of the Red Hot Chili Peppers and players interested in unusual short-scale basses.

Fleabass has 4 products cataloged on Equipboard, including Electric Basses. Their gear is featured by 7 artists, with the strongest followings in Rock, Funk / Soul, and Electronic. Notable users include Flea, Davie504, and Murray Cook.
