Lyon Olympique Universitaire Rugby or LOU is a French professional rugby union team based in Lyon that currently competes in the Top 14, the highest level of the country's professional league system, having been most recently promoted for the 2016–17 season after winning the 2015–16 title of the second-level Pro D2.

Le LOU, as it is traditionally known, is one of the oldest sports clubs in France and among the first outside Paris to have set up a rugby section.

The rugby club took part in three successive French championship finals (1931–33), losing the first one to Toulon (3–6) but winning the next two against Narbonne (9-3 and 10–3).

It then played in lower amateur leagues until it was promoted back to the second professional division (Pro D2).
