Guitar Hero: On Tour is a series of music video games based on the Guitar Hero series for the Nintendo DS handheld game system. The series is developed by Vicarious Visions and distributed by RedOctane and Activision. Three games in the series have been released since June 2008: Guitar Hero: On Tour, Guitar Hero On Tour: Decades and Guitar Hero On Tour: Modern Hits.

As with other games in the Guitar Hero series, the player is challenged to play through the lead or bass guitar portions of rock songs by matching colored notes that scroll on screen towards the player in time with physical actions to score points and keep the virtual crowd pleased. While the console versions of Guitar Hero use a separate guitar-shaped peripheral, Vicarious Visions developed a "Guitar Grip" unit that slips into the Game Boy Advance port on the DS or the DS Lite to be used with the games; the Grip is incompatible with the Nintendo DSi and Nintendo 3DS. The Guitar Grip provides a strap to hold the game unit while providing the player with four fret buttons; the player uses the fret buttons in combination with using the stylus to simulate strumming on the touch-sensitive screen of the DS. Each game features more than 25 songs, with some variation in track lists depending on the region of release, and multiple single-player modes. The local wi-fi capabilities of the DS are used for multiplayer mode, and allow a player to use songs from one installment of the series in competitive modes with a player with a different installment.

The core gameplay remains unchanged from the other games in the series. The Guitar Grip is required to play the game and comes as part of a bundle that can be purchased for each installment. The Grip is designed for the DS Lite, but features a small adapter that can be removed for use in the older Nintendo DS models. Four fret buttons are located on the side of the unit near the cartridge slot. This is one less than the normal five frets, included an orange-colored one, managed by other Guitar Hero controllers. A wriststrap is attached to the underside to provide support while playing. The player holds the unit in a vertical book orientation (similar to Ninja Gaiden: Dragon Sword or Hotel Dusk: Room 215), and uses a special guitar pick-shaped stylus to strum on the touchscreen of the DS with their free hand. The "note highway" and the performance of the chosen character in the band are shown on the opposite screen. As notes scroll down on the note highway, the player must press the correct fret button and strum the touchscreen at the same time to successfully score points. While holding a long note, the player can also use the touch screen to apply a whammy effect by moving the stylus across the on-screen whammy bar or anywhere on the screen. After the player has successfully hit a selected series of notes, he or she will gain "Star Power" which doubles their score until the meter has run out. This is activated by yelling or blowing into the DS's microphone, by pressing any of the face buttons on the DS, or by tapping the Star Power meter on the touchscreen.
