The British Rail Class 222 Meridian is a type of diesel-electric multiple-unit high-speed passenger train capable of 125 mph (200 km/h). Twenty-seven sets were built by Bombardier Transportation in Bruges, Belgium, from 2003 to 2005.

The Class 222 is part of the Bombardier Voyager family, bearing a similarity to the Class 220 Voyager and Class 221 Super Voyager trains currently operated by CrossCountry and Grand Central. Originally built for Midland Mainline and Hull Trains, today the class is operated by Lumo and East Midlands Railway who brand it Meridian.
