In 1889, football and tennis departments were included in the club, and it changed name to the present Odense Boldklub.

This time the club had the players to be a top team in the best league under the reign of coach Richard Møller Nielsen.

In 1989, the club won the Danish championship again ahead of defending champions Brøndby IF under new manager Roald Poulsen.

The profiles of Roald Poulsen's team included, apart from Lars Høgh, the midfielder Ulrik Moseby, the big defender Johnny Hansen, and the young forward Per Pedersen, who became the most expensive OB player sold, when he was bought by English team Blackburn Rovers for £2.3 million in 1997.

They won the Danish Cup final against AaB after two goalless matches, extra time and penalty shootout.

As the Danish Football Association (DBU) restructured the Superliga before the 1995–96 season, and introduced a league format of 33 games spanning a full year; OB won bronze once more.

OB finished second in the 2008–09 season, which led to a two-game playoff with Genoa for participation in the 2009–10 UEFA Europa League.

After a fantastic start of the season the club disappointingly did not take the first place, due to a string of lost and drawn games in the spring of 2010.

OB were drawn to face Scottish club Motherwell in the fourth qualifying round of the 2010–11 Europa League.

In the 1994–95 UEFA Cup, OB reached beyond the first round in a European tournament for the first time in club history.

In the second round, they drew 1–1 in the away game against Northern Irish club Linfield and won 5–0 at home, including two long-range goals by defender Steen Nedergaard.

The first match was played at a sold-out Odense Stadion, and OB surprisingly scored on a corner kick in the first half.

In the second half, Real Madrid quickly scored two goals, but OB managed to come back into the game, when they equalized to 2–2.

With a goal by Morten Bisgaard shortly before stoppage time, OB achieved the needed 2–0 victory, and advanced to the quarter-final.

OB's victory attracted attention in great parts of Europe and in Denmark the event was named "The Miracle in Madrid."
