Culex erraticus, which translates in English to Erratic Mosquito, is a species of mosquito in the family Culicidae. It is widespread in Florida, but rare in the northeastern United States. The mosquito ranges in the north from Connecticut and Ontario, west to Nebraska, and south to Mexico, Central America, and South America. In addition, it is found in southernmost California.

The females can be aggressive biters. They take blood meals from birds, mammals, amphibians, and reptiles. The mosquito is frequently infected with the virus EEEV, and may be a public health concern for its potential to transmit this arbovirus to people.

Culex erraticus mosquitoes lay eggs in floating clusters called “egg rafts” on the surface of standing water, usually by laying them on the edges of aquatic plant leaves.

These mosquitoes are known overwinter in gopher tortoise burrows from October through February in Central Florida.{{cite journal |last1=McNamara |first1=Timothy D |last2=Mosore |first2=Mba-tihssommah |last3=Urlaub |first3=Alexander |last4=Lashley |first4=Marcus A |last5=Burkett-Cadena |first5=Nathan D |last6=Reeves |first6=Lawrence E |last7=Martin |first7=Estelle M |title=Culex erraticus (Diptera: Culicidae) utilizes gopher tortoise burrows for overwintering in North Central Florida |journal=Journal of Medical Entomology |date=13 January 2024 |doi=10.1093/jme/tjad174 |url=https://academic.oup.com/jme/advance-article/doi/10.1093/jme/tjad174/7529013?login=false|doi-access=free |pmc=10936169 }}
