Season 5 of Codename: Kids Next Door started on September 25, 2005. The Christmas special aired on December 6, 2005, three years after the series' official television premiere. The last episode of the season aired on August 24, 2006.
Season 5, like the other seasons, has thirteen episodes in all. Nine of these are two eleven-minute episodes, while the other four are each twenty-two minutes long.
