Google Street View is a technology featured in Google Maps and Google Earth that provides interactive panoramas from positions along many streets in the world. It was launched in 2007 in several cities in the United States, and has since expanded to include all of the country's major and minor cities, as well as the cities and rural areas of many other countries worldwide. Streets with Street View imagery available are shown as clickable blue lines on Google Maps.

Google Street View displays interactive panoramas of stitched VR photographs. Most photography is done by car, but some is done by tricycle, camel, boat, snowmobile, underwater apparatus, and on foot.

Street View had its inception in 2001 with the Stanford CityBlock Project, a Google-sponsored Stanford University research project. The project ended in June 2006, and its technology was folded into Street View. The technology was launched on May 25, 2007, in the United States.

In May 2008, Google announced that it was testing face-blurring technology on its photos of the streets of Manhattan. The technology uses a computer algorithm to search Google's image database for faces and blur them. Street View was integrated into Google Earth 4.3, the Maps application on the Apple iPhone, and the Maps application for the S60 3rd Edition. In November, the drag-and-drop Pegman icon was introduced as the primary user interface element for connecting from Maps' 2D view into Street View's 3D view. When Pegman is dropped onto a particular set of coordinates in Google Maps for which Street View data is available, Street View opens and takes over the whole map window.

In 2009, a full-screen option and Smart Navigation were introduced. Smart Navigation allows users to navigate around the panoramas by double-clicking with their cursor on any place or object they want to see. In May 2011, indoor views of businesses (Google Business Photos) were announced. After the pilot phase of several months, the project was rolled out in autumn.

With the release of Android 4.2 in November 2012, Google invited users to contribute panoramas of their own using supported devices. Google highlights user-contributed panoramas with blue circle icons on Maps. The company also created a website to highlight places in the world where one can find them. In 2013, businesses such as shops, cafés and other premises can pay a photographer to take panoramic images of the interior of their premises, which were then included in Street View. Google sets up a program to let third parties borrow the Street View Trekker (a backpack-mounted camera). Business interior views are shown as small orange circles. In 2014, Street-level imagery from the past can now be optionally seen, if available, for a given street view.

In 2015, a partnership was announced between Street View and the environmental monitoring company Aclima. Cars carry sensors to detect pollutants such as nitrogen dioxide, ozone, and particulates. In October, support for Google Cardboard was announced, allowing users to utilize Street View in 360-degree virtual reality.

In 2017, imagery inside the International Space Station was added to Street View. In August 2017, Google also allowed users to create their own Street View-like blue paths for the connected photospheres that are sufficiently close to one another.
