Phidippus otiosus is a species of jumping spider that is found in southeastern North America.

Females position their single egg sac under the bark of oak and pine trees.

[4] Phidippus otiosus naturally occurs in the southeastern United States from Florida and Texas to North Carolina.

[5] However, this species is sometimes exported with plants such as Tillandsia, and has been found in countries as remote as Sweden[6] and Germany.

The species name is possibly derived from Latin otium "leisure, peace, quiet" + the suffix -osus "full of, prone to", or from Ancient Greek oto- "ear", referring to the tufts of black hair.
