How I Met Your Mother produced 208 total episodes across its nine-season run. The episode count covers the complete CBS series, from the 2005 pilot through the two-part series finale, “Last Forever,” which aired in 2014.
The sitcom premiered on September 19, 2005, and concluded on March 31, 2014. Although most episodes used the show’s familiar half-hour format, the series sometimes presented hour-long broadcasts or multi-part stories. Those unusual runtimes can make the total seem different depending on whether a listing counts broadcast installments, story segments, or production entries.
The show’s nine seasons were not evenly sized. Several seasons had 22 episodes, while later seasons included larger episode orders. Season 9 was especially notable because its story unfolded over a single wedding weekend and included many flashbacks and flash-forwards.
Another frequent source of confusion is the distinction between episodes produced and episodes aired. Reference lists commonly summarize the finished series as 208 episodes, while specials, alternate endings, deleted scenes, and soundtrack material are not additional regular episodes.
