The Challenge Tour is the second tier men's professional golf tour in Europe. It is operated by the PGA European Tour and as with on the main European Tour and the European Seniors Tour, some of the events are played outside of Europe. World ranking points are awarded for high finishes in Challenge Tour events.

The tour was introduced in 1986 and was initially called the Satellite Tour. The Order of Merit was introduced in 1989, with the top five players on it winning membership of the European Tour for the following season. The following year the tour was renamed the Challenge Tour. Up to 1993 the Challenge Tour Rankings were based on each players' best several results, but since 1994 it has been a straightforward money list, with all results counting. In 2008 the total prize fund was €6,017,393.

Players who are successful on the Challenge Tour qualify for membership of the European Tour the following year. The top-20 players in the rankings are said to have "gained their tour card"; in reality, the top 15 qualify for most tournaments, 16-20 somewhat fewer, although the categories are re-ranked midway through the season. The final 5 places were added for the 2005 season - previously the top-15 only qualified. Players finishing 21-45 may also gain qualification for occasional low-prize money European Tour Events. Players who win three Challenge Tour events in a season are fast tracked onto the main tour immediately.

One competitive level down from the Challenge Tour there are three third-level developmental tours, the Alps Tour, the EPD Tour and the PGA EuroPro Tour, each of which is based in a different region of Europe. Each season the top five players from the Order of Merit of each of these tours wins a place on the Challenge Tour for the following season. The Challenge Tour also has an annual Qualifying School.
