Hertz CEO and president John Tague is retiring in the New Year and will be replaced by an external executive.
Kathryn V. Marinello will join the car rental giant from outsourcing firm Stream Global Services, where she is CEO.
She takes over on January 3, 2017.
Tague had served as CEO since late 2014.
Marinello was previously the CEO of human resources software provider Ceridian and also held senior level positions at General Electric.
"I am excited about Hertz and its prospects with Kathy at the helm. Kathy has a history as a proven CEO and I believe she is the right person to lead Hertz as we move forward," said Carl Icahn, Hertz largest shareholder.
"Her consistent track record of successes in consumer and financial services, as well as technology businesses, is impressive. She was extremely well-regarded at GE and successfully turned around Ceridian and Stream."
