COO stands for Chief operating officer, a job title abbreviation.

Second-ranking executive in many companies, in charge of day-to-day operations such as production, supply chain, customer service and internal processes, turning strategy set with the CEO into execution. The COO is often seen as a potential successor to the CEO.

Example: As COO, she oversees the company's 14 distribution centers and its 3,000-person customer service operation.

Usage notes

The scope of the role varies more than any other C-suite title, and some companies have no COO at all. Well-known COOs include Tim Cook at Apple before he became CEO in 2011 and Sheryl Sandberg at Facebook (now Meta) from 2008 to 2022. Pronounced as letters.
