Rosy Business (Chinese: 巾幗梟雄; Jyutping: gan1 gwok3 hiu1 hung4) is a 2009 Hong Kong period television drama produced by Lee Tim-sing and TVB. Comprising 25 episodes, it originally aired on the Jade network from 27 April to 29 May 2009.

Set in Eastern China during the mid-19th century, Rosy Business follows the mercantile Chiang family, owners of Wuxi's largest rice business Hing Fung Nin. After falling ill, patriarch Chiang Kiu temporarily hands over his leadership to his fourth wife Hong Po-kei, which incurs conflict with his other wives and sons. Meanwhile the impoverished coolie Chai Kau becomes an important figure in assisting Hong Po-kei in protecting the family business from crumbling during the Taiping Rebellion. The script was inspired by the successful Chinese television series The Grand Mansion Gate (Chinese: 大宅門).

The final two episodes were aired back-to-back as a two-hour finale, including a cast interview with Scoop (東張西望). A commercial success, the final week of broadcast peaked at 47 TVRs with 3 million live viewers, becoming the second highest-rated television drama in Hong Kong of 2009. It stars Best Actress winners Sheren Tang, Nancy Wu, and Kara Wai. Rosy Business received twelve TVB Anniversary Award nominations and eight top 5 nominations, winning six of them, becoming the biggest winner of the year. The awards include Best Drama, Best Actress (Sheren Tang), Best Actor (Wayne Lai), Best Supporting Actress (Susan Tse), My Favourite Male Character (Lai), and Most Improved Male Artiste (Ngo Ka-nin). An indirect sequel, No Regrets, was released as a grand production and TVB's anniversary series in 2010.
