Stouffville is one of the seven train lines of the GO Transit system in the Greater Toronto Area, Ontario, Canada. Its southern terminus is Union Station in Toronto, and its northern terminus is in Lincolnville in Whitchurch-Stouffville. There are bus connections from almost every station via Go Transit Buses, Toronto Transit Commission, and York Region Transit.
Like its sister the Barrie line, commuter service along the Stouffville line corridor was originally provided by Via Rail. On September 7, 1982, Via service on both routes was discontinued and replacement service, then just a single weekday run on each corridor, was started by GO Transit.
On 29 June 1998, GO Transit restored full service to the Lakeshore lines, and terminated service to Danforth and Scarborough on the Stouffville line—these stations were fully integrated into the Lakeshore East line route schedule.
On December 13, 2007, the government of Ontario announced funding to Metrolinx for network expansion, which included $20 million to build a second track to enable all-day two-way service between Union Station and Markham. On September 2, 2008, the line's northern terminus was extended northwards from Stouffville to Lincolnville.
In April 2011 GO representatives stated that ultimately GO would like to run an all-day service on the Stouffville line, however they described this as "in the distant future". As of April 2013 the Stouffville service includes six southbound morning trains and six northbound afternoon trains. Service to and from Unionville includes one additional southbound morning train and two additional northbound afternoon trains. In June 2013 GO held a first "Public Information Centre" of an environmental assessment study for expanding rail service in the Stouffville Corridor. This represented the completion of the second of five stages of work to implement expanded service, and recommended adding double track segments and other improvements between Union Station and Unionville to support increased train service levels.

Distances are given in kilometres.
The line begins at Union Station and follows the Lakeshore East line to Scarborough Junction, just east of Scarborough GO Station, without stopping at any stations on that line. It then branches north onto the Metrolinx-owned Uxbridge Subdivision, originally the Toronto and Nipissing Railway. North of Unionville station, the route heads roughly north-east in the direction of the Lincolnville terminus.
