Lupin the 3rd Part II is a Japanese anime television series produced by Tokyo Movie Shinsha. Part of the Lupin III franchise, it is the second anime television adaptation of the Lupin III manga series created by Monkey Punch. Although originally broadcast as simply Lupin III (Japanese: ルパン三世, Hepburn: Rupan Sansei), the series is now often referred to as New Lupin III (新 ルパン三世, Shin Rupan Sansei) by Japanese fans. Among English-speaking fans, the series is commonly known as the "Red Jacket" series in reference to Lupin's outfit.

The series contains 155 episodes, which aired between October 3, 1977, and October 6, 1980, on the Japanese television network Nippon Television. Episodes 145 and 155 were the first to appear in the United States on VHS in 1994, released by Streamline Pictures separately as Lupin III: Tales of the Wolf and together as Lupin III's Greatest Capers. In 2003, Pioneer Entertainment licensed and released 79 episodes in North America, some of which were broadcast on Adult Swim. The series was picked up by Discotek Media, who released all 155 episodes to DVD between 2017 and 2020.
