The Ford Focus ST is the sport-focused variant of the Ford Focus, produced across multiple generations, most notably from 2005 onward. It is powered by turbocharged four-cylinder engines, ranging from a 2.0-liter Duratec inline-four in earlier generations to a 2.3-liter EcoBoost in later models, producing 252–276 horsepower, paired exclusively with a 6-speed manual transmission. The Focus ST emphasizes agile handling, precise steering, and driver engagement in a compact, practical hatchback format.

Key features include sport-tuned suspension, a limited-slip differential in newer models, performance brakes, and aerodynamic body enhancements such as a rear spoiler and front splitter. Its driver-focused cockpit, combined with responsive turbocharged power and a lightweight chassis, makes the Focus ST a capable hot hatch for both everyday driving and spirited performance on the track or back roads.
