A hybrid transmission arrangement for a motor vehicle (30) includes a first transmission group (12), a second transmission group (18), a third planetary gear set (PS3), and a first electric machine (EM1). The first transmission group (12) includes a first input (14), a first output (16), and a first planetary gear set (PS1). The first input (14) is connectable to an internal combustion engine (VM). The second transmission group (18) includes a second input (20), a second output (22), and a second planetary gear set (PS2). The second input (20) is connected to the first output (16) of the first transmission group (12). The third planetary gear set (PS3) includes a first element (S3;H3I), a second element (H3;S3I), and a third element (P3;P3I). The third planetary gear set (PS3) is interlockable using a first shift element (E) and arranged coaxially to a first axis (A1). The first element (S3;H3I) is connected to the first electric machine. The second element (H3;S3I) is connected to the second output (22). The third element (P3;P3I) is connected to a drive output (Ab) of the hybrid transmission arrangement (10).
