Naruto Shippūden: Narutimate Accel (NARUTO-ナルト-疾風伝 ナルティメットアクセル, Naruto Shippūden: Narutimetto Akuseru) is a Japanese-only game and the fourth installment in the Narutimate Hero (Ultimate Ninja) series.

It is also the second Naruto game based on the Naruto: Shippūden anime series, which is based on the second part of the manga. The game was released on April 5, 2007 in Japan.

The game was first seen in issue #2006-52 of Weekly Shonen Jump[5] along with information about the Naruto: Shippūden anime and related merchandise.

In addition to elements established in previous Narutimate Hero games, Narutimate Accel offers several new twists to combat. When two opponents clash, they will begin a series of high-speed attacks, appearing as a pair of blurs dueling across the stage. The winner is determined by a game of Rock, Paper, Scissors.

There is also the inclusion of the "Awakening Ougi." When certain conditions are met, a character may trigger an Awakening Ougi. These techniques are more powerful than the standard Ougis and, as the name implies, "awakens" a character's powers (i.e. Naruto's tailed-fox form with overpowering red chakra).
