Yes, "Rocky Balboa" is a continuation of the "Rocky" film series. It's the sixth installment in the franchise, released in 2006, and picks up the story of Rocky several years after the events of "Rocky V."

While it's a direct sequel, it's also somewhat of a standalone film. It doesn't rely heavily on events from previous films and explores new themes and challenges for Rocky.
