Google Fiber is Google's fiber-to-the-premises service in the United States, providing broadband internet and cable television to a small and slowly increasing number of locations. As of end of 2014, Google Fiber had 29,867 television subscribers. As of Oct 2015, up to 120,000 customers have been estimated.

The service was first introduced to the Kansas City metropolitan area, including 20 Kansas City area suburbs within the first 3 years. Initially proposed as an experimental project, Google Fiber was announced as a viable business model on December 12, 2012, when Google executive chairman Eric Schmidt stated "It's actually not an experiment, we're actually running it as a business," at the New York Times' DealBook Conference.

Google Fiber announced expansion to Austin, Texas and Provo, Utah in April 2013, and subsequent expansions in 2014 and 2015 to Atlanta, Charlotte, Raleigh, Durham, Nashville, Salt Lake City, and San Antonio.

On August 10, 2015, Google announced its intention to restructure the company, moving less central services and products into a new umbrella corporation, Alphabet Inc. As part of this restructuring plan, Google Fiber would become a subsidiary of Alphabet, and may become part of the "Access and Energy" business unit.
