No Surrender 2008 was a professional wrestling pay-per-view (PPV) event produced by the Total Nonstop Action Wrestling (TNA) promotion that took place on September 14, 2008 at the General Motors Centre in Oshawa, Ontario, Canada. It was the fourth event under the No Surrender name, TNA's first PPV to take place outside the United States, and the ninth event in the 2008 TNA PPV schedule. Nine professional wrestling matches were featured on the event's card, four of which were for championships.

The main event was a Three Ways to Glory match for the TNA World Heavyweight Championship with the champion Samoa Joe defending the title against Christian Cage and Kurt Angle. Joe successfully retained the title at the show. A.J. Styles defeated Frank Trigg in a Mixed Martial Arts match also on the show. The TNA World Tag Team Championship was defended by Beer Money, Inc. (James Storm and Robert Roode) against The Latin American Xchange (Hernandez and Homicide). Beer Money, Inc. retained the championship at the event. TNA held a Ladder of Love match for SoCal Val, in which Sonjay Dutt defeated Jay Lethal. The TNA X Division Championship was also defended in a Three Way match by Petey Williams against Sheik Abdul Bashir and Consequences Creed, which Bashir won to become the new champion.

No Surrender is remembered for being the first TNA PPV held outside the United States and for the return of Jeff Jarrett to TNA television. 20,000 was the reported figure of purchasers for the event by the Wrestling Observer Newsletter. No Surrender had an attendance of 3,500 people. Jason Clevett of the professional wrestling section of the Canadian Online Explorer rated the show a 3 out of 10, which was lower than the 7 out of 10 given to the 2007 edition by Chris Sokol. In regards to the overall show, Clevett said that "TNA’s pay per view debut in Canada was one of the weakest shows in recent memory, overwhelmed by horrible overbooking by TNA that once again proves that they do not know what their fanbase wants."In October 2017, with the launch of the Global Wrestling Network, the event became available to stream on demand.
