An exhaust gas heat exchanger may include a housing and a heat exchanger block arranged therein, the heat exchanger block including tube plates and a tube bundle having a plurality of flat tubes held at longitudinal ends of the flat tubes in rim holes formed in a complementary manner thereto in the tube plates. A first flow path for exhaust gas may extend in the flat tubes, and a second flow path for coolant may extend around the flat tubes and within the housing. The housing may include a plurality of latching contours, which interact with a plurality of counterpart latching contours arranged on an associated tube plate to fix the tube plates and the heat exchanger block on the housing.
