Which is the correct name of the lizard in the picture, seen on TV commercials in the United States?

The green lizard seen in the picture that is used in commercials on TV in the US is officially called the 'GEICO gecko' but the correct answer to the question is simply the name of the lizard- GECKO.

The company that uses the lizard in its advertising is called GEICO. Advertising campaigns are known for surreal humor and satire featuring the company's mascot. A common tag line that is quoted in the TV commercial for promotional purposes by GEICO is "15 minutes could save you 15% or more on car insurance".

The real animal, a species of lizards, belongs to the 'infraorder Gekkota' found in warm climates throughout the world.

The 'GEICO gecko' first appeared in 2000, during the Screen Actors Guild strike that prevented the use of live actors. The original commercial features the gecko, who climbs onto a microphone on a podium and utters, "This is my last plea; I am a gecko, not to be confused with GEICO, which could save you hundreds on car insurance. So, STOP CALLING ME!" before licking his eye.

In later advertisements on TV, Dave Kelly, a British radio presenter and DJ from Northampton, England was used as the voice of the gecko in TV commercials.
