Faustina Charles Mfinanga (born November 9, 1992), popularly known by her stage name Nandy is a Tanzanian singer, songwriter and actress. The name Nandy is shortened from her traditional name Nandera. She was born and raised in the town of Moshi, Tanzania in Kilimanjaro Region. She won the All Africa Music Awards twice in the best female artist in East Africa category in 2017 and 2020.

Her career in music kicked off when a common friend introduced her to Ruge Mutahaba, CEO of Tanzania House of Talent (THT). This is where she met Emma the Boy, who produced her first mainstream single, Nagusagusa. The song became a huge hit within a week of its release. In early 2016 she participated in a singing competition Tecno own the Stage. The contest featured contestants from all over Africa and during the finals in Lagos, Nigeria, Nandy emerged as the first runner-up.

In 2017 she released her hit single One Day which spearheaded her career and gave her a couple of opportunities as she was one of the few artists who participated in Coke Studio Africa in 2017 and later the same year she was nominated in the All Africa Music Awards as best female eastern Africa and won. In January 2023, Nandy launched her own record label named "The African Princess" and signed Yammi, who is the label's first signee. Read more on Last.fm.
