[4][5] Since retiring as a player, Galthié has coached Stade Français, Montpellier and Toulon in the French Top 14 competition.

He was called into France's 1991 Rugby World Cup squad, replacing the injured Pierre Berbizier.

Galthié was a crucial member of the French team that upset New Zealand in the semifinal of the 1999 Rugby World Cup at Twickenham.

In 2000, Colomiers reached the French championship final, but Galthié had to watch from the stands due to a knee injury.

Galthié returned for the next game, the quarterfinal against Ireland which they won convincingly, but in the semi-final they lost to England 24–7.

The following season Stade Français were beaten by Toulouse in the Top 14 semi-final, and they were knocked out of the Heineken Cup by Leicester.

He became a TV pundit with the French public national channel France 2 and private radio Europe 1.
