Esky is an Australian brand of portable coolers. The term "esky" is also commonly used in Australia to generically refer to portable coolers or ice boxes and is part of the Australian vernacular, in place of words like "cooler" or "cooler box" and the New Zealand "chilly bin". The term derives from the word Eskimo.

The Esky was created by Malley's, a Sydney refrigeration business. Some historians have credited Malley's with the invention of the portable ice cooler. According to the company, the Esky was "recognised as the first official portable cooler in the world." The company's own figures claim that by 1960, 500,000 Australian households owned one (in a country of approximately 10 million).

Outdoor recreation company Coleman Australia bought the Esky brand from Nylex Ltd after the company went into administration in February 2009. Esky has been producing coolers since 1952. Coleman still produces most of the Esky line in Melbourne. The sale was seen as symptomatic of the decline of Australian made goods due to cheaper imports being available.
