An exhaust gas muffler of an internal combustion engine, including a muffler housing having an exhaust gas inlet and an exhaust gas outlet and including a first Helmholtz resonator made of a first housing portion that delimits a first Helmholtz volume and includes a first coupling pipe. At least one second Helmholtz resonator is provided made of a second housing portion that delimits a second Helmholtz volume and includes a second coupling pipe via which the second Helmholtz volume can be coupled to an exhaust gas flow A of the exhaust gas inlet. The second coupling pipe is arranged at least partly within the first coupling pipe, and both coupling pipes delimit an annular gap R via which the first Helmholtz volume can be coupled to the exhaust gas flow A.
