<P> The Seahawks have won 10 division titles and three conference championships . They are the only team to have played in both the AFC and NFC Championship Games . They have appeared in three Super Bowls : losing 21 -- 10 to the Pittsburgh Steelers in Super Bowl XL , defeating the Denver Broncos 43 -- 8 for their first championship in Super Bowl XLVIII , and losing 28 -- 24 to the New England Patriots in Super Bowl XLIX . They are also the first , and to date only , post-merger expansion team in NFL history to play in consecutive Super Bowl games . </P>
