Out of necessity to have an alternative sport in winter, frozen rivers made rowing naturally impossible, the rugby department of the club was formed in 1919.

In 2013–14 the team qualified for the championship and the play-offs once more, defeating TSV Victoria Linden 101–10 in the first round and losing to Berliner Rugby Club in the quarter-finals.

The former England international Phil Christophers who made his debut in 2002 started his rugby career with RG Heidelberg, being the son of a German mother and English father.

In the 2008–10 campaign, Güngör, Weselek, Takaendesa, Coly, Wilhelm and Brenner all appeared for the RGH and Germany again, while Pierre Faber and Fabian Heimpel were new additions to the club's list of internationals.
