The Google Glass was a brand of smart glasses developed and sold by Google between 2013 and 2023. The smart glasses were developed by Google X by a team led by Janco van der Merwe. The optical head-mounted headset was worn like a normal pair of eyeglasses, and the information was displayed in the user's field of vision providing a hands-free device. The glasses were controlled by voice commands and a built-in touchpad, and used audio, visual and location inputs to relay information to the user. The Google Glass used the Android operating system providing a user-friendly interface similar to a smartphone. They also featured a camera that was able to record and take high-resolution videos and photographs.

The Google Glass was first publicly announced in April 2012. The first Google Glass available was a prototype to 8,000 "Glass Explorers" in April 2013, before becoming available to the public in May that year. Further Enterprise Editions were released in 2017 and 2019, aiming the smart glasses at use in industrial settings such as manufacturing, medicine, and education.

Sales of the Google Glass were suspended in March 2023.
