Keolis is a French transportation company that operates public transport systems all over the world. It manages bus, rapid transit, tram, coach networks, rental bikes, car parks, water taxi, cable car, trolleybus, and funicular services. Based in Paris, France, the company is 70% owned by SNCF and 30% owned by the Caisse de dépôt et placement du Québec.

Keolis operates a number of networks in France (Transports Bordeaux Métropole in Bordeaux, the Lyon public transport on behalf of SYTRAL, the public transport service for the Greater Rennes area since 1998, Transpole in Lille, and the entire mobility chain in Dijon).

It also manages various rail networks internationally, such as the commuter rail in Boston, the Hyderabad Metro, the Melbourne tramway, the Docklands Light Railway in London, the Pujiang line (Shanghai Metro), the Nottingham tramway, and the Manchester tramway.

Keolis was formed from several former companies:

• Société des transports automobiles, which was created in 1908, and its subsidiary Société générale des transports départementaux
• Lesexel, an electricity company created in 1911 to support the development of tramways
• Société de transports routiers de voyageurs (STRV), a subsidiary of SCETE [fr] and later SNCF, which was renamed Cariane [fr] in 1988 during its merger with STV

These companies underwent a series of reorganizations, mergers and acquisitions, which resulted in two companies: VIA-GTI [fr], focused primarily on urban transport, and Cariane, specialized in interurban public transport.

In 1999, SNCF became the leading shareholder in VIA-GTI, which merged with Cariane in 2001 to become Keolis. In 2005, through its stake in GoVia, Keolis became co-owner of the South Eastern rail franchise in the United Kingdom. In 2006, Keolis won the franchise for Hellweg Net in Germany and later on for Maas-Rhein-Lippe Net and Teutoburger-Wald Net in Deutschland and Nederland. In 2007, Keolis acquired City-Trafic in Denmark. In 2008, Keolis took control of Eurobus Holding in Belgium. In 2009, Keolis set up operations in Melbourne, Washington, D.C., Bergen and Bordeaux. In 2010, EFFIA (car parks company) became a Keolis subsidiary.

In 2018, the company generated revenues of €5.9 billion and had 63,000 employees. Keolis has been led by Marie-Ange Debon since September 2020.

In 2018, Keolis started operating the Pujiang metro line (formerly known as 8.3), the first automatic metro line in the Shanghai network, and started a contract to operate the Wales & Borders rail network in Wales until the nationalisation of day to day services in February 2021, with Keolis retaining a partnership with the new national operator until the original contract expires.

Keolis Danmark is the second biggest bus operator in Denmark with 500 buses and 1,500 employees. Keolis entered the Danish market in 1999 when they bought 49% of the Danish bus operator City-Trafik.

Eurobahn used Stadler Flirt electric multiple units and Bombardier Talent diesel cars to serve these lines. During December 2007, the joint venture was dissolved; at this point, Rhenus took ownership of the bus operations and two railway contracts while Keolis gained full ownership of Eurobahn and the remaining contracts.

In partnership with Amey, Keolis operates both the Docklands Light Railway and Manchester Metrolink concessions. Furthermore, Keolis is part of the Tramlink Nottingham consortium that commenced operating the Nottingham Express Transit tram operation in December 2011. Specifically, operations have been sub-contracted to Nottingham Trams Limited, a consortium of Keolis (80%) and Wellglade (20%).

In May 2018, the Wales & Borders franchise was awarded to KeolisAmey Wales, who received a contract valued at £5 billion covering a 15-year period starting on 14 October 2018. This contract included the provision of investment in the Welsh network, including £800M into new rolling stock, £194M to modernise 247 stations and build five new Metro stations, the running of 285 extra services between Monday and Friday along with 294 extra Sunday services.

On 31 May 2020, an Emergency Measures Agreement was approved to assist KeolisAmey Wales; it detailed that the Welsh Government will spend up to £65 million over the next six months to ensure trains continue to operate on the franchise. On 7 February 2021, the franchise was nationalised by the Welsh Government and transferred to a publicly owned operator of last resort, Transport for Wales Rail, with Amey retaining an involvement in delivering key infrastructure projects related to the Core Valley Lines.

Keolis America is based in Boston, Massachusetts. It does business as Keolis North America, operating public transportation contracts in both the U.S. and Canada. In the U.S., its subsidiaries operate commuter rail systems in Virginia and Massachusetts, as well as fixed-route and shuttle bus systems in several states. In Nevada, Keolis operates bus services along the Las Vegas strip through a contract with the Regional Transportation Commission.

On 16 October 2009, the Virginia Railway Express (VRE) Operations Board approved an $85 million contract with Keolis Rail Services America to operate and maintain VRE trains for five years. Keolis began operating VRE on 12 July 2010 after a two-week delay, ending Amtrak's 18-year tenure as operator. Both Amtrak and Keolis had staffed the VRE lines with about 80 employees. However, during the bidding, a group of Holocaust survivors and Maryland politician Heather Mizeur called for investigations into SNCF's role in transportation of Nazi prisoners to concentration camps during the Second World War before the Keolis contracts could move forward. The operator of the train line, Amtrak, also challenged the propriety of hiring a foreign company.

It has also bid to run some California commuter rail segments and two MARC lines in Maryland, even though with the latter, the company is running into similar issues with the VRE bidding. Another group of Holocaust survivors, led by now-deceased Leo Bretholz also requested investigations of SNCF's involvement in the conflict. As a result, a law was passed to enforce this, leading to major criticism because SNCF had already documented their role in the deportation and had in fact released their archives for research and educational purposes in 1996. Eventually however, Keolis would lose to Canadian company Bombardier Transportation.

On 29 November 2011, Keolis Transit America, Keolis' US subsidiary, announced acquisition of Tectrans Inc., a California-based privately held provider of contract transportation services. Tectrans holdings included in the acquisition included Mobility Plus Transportation, Western Transit Systems, and Diversified Transportation.

On 8 January 2014, the Massachusetts Bay Transportation Authority awarded Keolis Commuter Services a contract to operate 664 miles of passenger service for $2.68 billion over eight years, with the possibility for two two-year extensions that could bring the total price to $4.3 billion. It began operating the MBTA Commuter Rail on 1 July 2014.

Keolis bus operations in the United States include Foothill Transit, OC Bus, and CapMetro Bus.
