Stadler FLIRT (German: Flinker Leichter Innovativer Regional-Triebzug, lit.'Fast Light Innovative Regional Train') is a passenger multiple unit trainset made by Stadler Rail of Switzerland. The baseline design of FLIRT is an electric multiple unit articulated trainset that can come in units of two to twelve cars with two to six motorized axles. The maximum speed is 200 km/h (125 mph). Standard floor height is 57 cm (22+716 in), but 78 cm (30+1116 in) high floors are also available for platform heights of 76 cm (29+1516 in).

The FLIRT train was originally developed for the Swiss Federal Railways and was first delivered in 2004. The trains quickly became a success and were ordered by operators in Algeria, Azerbaijan, Belarus, Canada, the Czech Republic, Estonia, Finland, Germany, Hungary, Italy, Lithuania, the Netherlands, Norway, Poland, Serbia, Slovenia, Sweden, Switzerland, the United Kingdom, and the United States. As of October 2021, more than 2500 units have been sold.

Aside from being electric (EMU), the FLIRT is available in diesel-electric (DEMU), battery-electric, bi-mode EDMU, tri-mode diesel/overhead electric/battery (see also: Stadler WINK), and more recently hydrogen fuel cell versions. Bi-mode models were first ordered by Italy's Aosta Valley region as (BTR.813), then by Greater Anglia as the British Rail Class 755, and Norske Tog. Tri-mode versions were first ordered by Transport for Wales (KeolisAmey). Hydrogen fuel-cell versions were first ordered by Arrow in San Bernardino County, California, USA.
