Looking Back in Anger (Chinese: 義不容情; lit. 'righteousness doesn’t permit feelings') was a 1989 Hong Kong TV series and one of the most watched TVB series by Chinese people in Hong Kong, Southeast Asia and around the world. Many factors contributed to the success of this series. As well as its tragic but memorable storyline, the series featured a strong cast, with Felix Wong, Deric Wan (who rose to fame with his role as the main antagonist), Carina Lau, Kathy Chow and Maggie Shiu. The popular theme song of the series "Yat sang ho kau" (一生何求) was sung by Danny Chan and later by Deric Wan himself.

In 2022, the drama was selected as one of ten classic TVB dramas being honoured for a new joint Youku and TVB programme.
