The Type 702 Berlin-class replenishment ship is a series of replenishment ships, originally designed and built for service in the German Navy (Deutsche Marine). Designed to support United Nations overseas missions, the Berlin class were initially to number four vessels. However, three hulls were cut from the initial order. The lead ship, Berlin, began construction in 1999 and entered service in 2001. The second hull, Frankfurt am Main, was re-ordered in 1998, began construction in 2000 and entered service in 2002. The third hull, Bonn, was ordered in 2008 to a modified design, began construction in 2010 and entered service in 2013. All three ships are in service and are based at Wilhelmshaven.

The Berlin-class design was selected as the basis for the Royal Canadian Navy's (RCN) replacement for the two former Protecteur-class auxiliary oiler replenishment (AOR) vessels which were retired in 2014. Two Berlin-class variants, described as Joint Support Ships, were ordered by the RCN to be built in Canada. As of 2023, both vessels are under construction.
