Nannostomus minimus, commonly known as the least pencilfish, is a freshwater species of fish belonging to the Lebiasinidae family of characins. It is restricted to Guyana, where it has been reported from the Potaro and Mazaruni Rivers.
N. minimus reaches a length of 23 mm. When described in 1909, it was the smallest of the known pencilfishes; that distinction has since passed to N. anduzei.
