2003 San Diego Chargers season

The 2003 San Diego Chargers season began with the team trying to improve on their 8–8 record in 2002. They finished the campaign 4th in their division and earned the #1 pick in the 2004 NFL draft. They played one game during the season, against the Miami Dolphins, at Sun Devil Stadium in Tempe, Arizona due to the Cedar Fire.

Oddly, this season marked the first time that the Chargers played the Jacksonville Jaguars, despite that team existing since 1995. This is largely due to old NFL scheduling formulas in place prior to 2002.
