M-Girls (Chinese: 四個女生), is a four-member Malaysian girl group that was formed in late 2000, releasing mainly Chinese New Year albums every year. Members of this group consist of Crystal Ong Shir Ching (王雪晶), Queenzy Cheng Koon Si (莊群施), Angeline Khoo Yen Nee (邱燕妮, AKA 阿妮 [Ah Ni]), and Cass Chin Yan Zi (陳金燕 AKA 金燕子 or 燕子), who originally left M-Girls in 2005 to study but later came back in late 2012. M-Girls rose in popularity due to the group's unique style, catchy songs, and collaborations with other famous Asian music stars like 四千金 (Four Golden Princesses) and Timi Zhuo. While M-Girls studio albums have been officially released in many different parts of the world, the group has been a longstanding victim to piracy and unlicensed, illegal distribution. As a result from this, and due to the increased trend of online video streaming, the group's music company, Starmedia, decided to stop producing additional M-Girls albums in 2014. This announcement came out during the release of the Chinese New Year album 真歡喜 (True Happiness) in February 2014, a couple of weeks after the release of their EP, My Way.
In 2015, M-Girls released one last CNY album, 新春佳期 (New Spring Holiday), through Starmedia. Afterwards, the group later on decided to part ways with the music company and established its own company, MG Entertainment. This new company's first album release was entitled 年來了 (The New Year is Coming), which came out in 2016.
As of 2017, the members of M-Girls are taking a break from working together a group and would not be producing any albums together, even for the 2018 CNY season. Instead, everyone is currently pursuing solo projects and endeavors for the time being.
