Google Play, also known as the Google Play Store or Play Store, and formerly known as the Android Market, is a digital distribution service operated and developed by Google. It serves as the official app store for certified devices running on the Android operating system and its derivatives, as well as ChromeOS, allowing users to browse and download applications developed with the Android software development kit and published through Google. Google Play has also served as a digital media store, with it offering various media for purchase (as well as certain things available free) such as books, movies, musical singles, television programs, and video games.

Content that has been purchased on Google TV and Google Play Books can be accessed on a web browser (such as, for example, Google Chrome) and through certain Android and iOS apps. An individual's Google Account can feature a diverse collection of materials to be heard, read, watched, or otherwise interacted with. The nature of the various things offered through Google Play's services have changed over time given the particular history of the Android operating system.

Applications are available through Google Play either for free or at a cost. They can be downloaded directly on an Android device through the proprietary Google Play Store mobile app or by deploying the application to a device from the Google Play website. Applications utilizing the hardware capabilities of a device can be targeted at users of devices with specific hardware components, such as a motion sensor (for motion-dependent games) or a front-facing camera (for online video calling). The Google Play Store had over 82 billion app downloads in 2016 and over 3.5 million apps published in 2017, while after a purge of apps, it is back to over 3 million. It has been the subject of multiple issues concerning security, in which malicious software has been approved and uploaded to the store and downloaded by users, with varying degrees of severity.

Google Play was launched on March 6, 2012, bringing together Android Market, Google Music, Google Movies, and Google Books under one brand, marking a shift in Google's digital distribution strategy. Following their rebranding, Google has expanded the geographical support for each of the services. Since 2021, Google has gradually sunsetted the Play brand: Google Play Newsstand was discontinued and replaced by Google News, Google Play Music was discontinued and replaced by YouTube Music on December 3, 2020, and Play Movies & TV was rebranded as Google TV on November 11, 2021.

By the end of 2017, Google Play featured more than 3.5 million Android applications. After Google purged many apps from the Google Play Store starting in 2024, there were 1.68 million Android applications in 2024. As of 2017, developers in more than 150 locations could distribute apps on Google Play, though not every location supports merchant registration. Developers receive 85% of the application price, while the remaining 15% goes to the distribution partner and operating fees. Developers can set up sales, with the original price struck out and a banner underneath informing users when the sale ends. Google Play allows developers to release early versions of apps to a select group of users, as alpha or beta tests. Users can pre-order select apps (as well as movies, music, books, and games) to have the items delivered as soon as they are available. Some network carriers offer billing for Google Play purchases, allowing users to opt for charges in the monthly phone bill rather than on credit cards. Users can request refunds within 48 hours after a purchase.

At the Google I/O 2013 Developer Conference, Google announced the introduction of Google Play Games. Google Play Games is an online gaming service for Android that features real-time multiplayer gaming capabilities, cloud saves, social and public leaderboards, and achievements. Its standalone mobile app was launched on July 24, 2013.

Google Play Books is an ebook digital distribution service. Google Play offers over five million ebooks available for purchase, and users can also upload up to 1,000 of their own ebooks in the form of PDF or EPUB file formats. As of January 2017^[update], Google Play Books is available in 75 countries.

Google Play Movies & TV was a video on demand service offering movies and television shows available for purchase or rental, depending on availability.
