<P> The Broncos were barely competitive during their 10 - year run in the AFL and their first seven years in the NFL . They did not complete a winning season until 1973 . In 1977 , four years later , they qualified for the playoffs for the first time in franchise history and advanced to Super Bowl XII . Since 1975 , the Broncos have become one of the NFL 's more successful teams , having suffered only seven losing seasons . They have won eight AFC Championships ( 1977 , 1986 , 1987 , 1989 , 1997 , 1998 , 2013 , 2015 , and three Super Bowl championships ( 1997 ( XXXII ) , 1998 ( XXXIII ) , 2015 ( 50 ) . However , the Broncos share the NFL record for most Super Bowl losses ( 5 ) with the New England Patriots . They have five players in the Pro Football Hall of Fame : John Elway , Floyd Little , Gary Zimmerman , Shannon Sharpe and Terrell Davis . </P>
