Eulaulah Donyll "Lalah" Hathaway (born December 16, 1968) is an American singer-songwriter. She is the first-born daughter of musician and soul singer Donny Hathaway.

She rose to fame in the 1990s with the release of her debut self-titled album, Lalah Hathaway (1990). The album's lead single "Heaven Knows" peaked in the top-five on the US Billboard Hot R&B/Hip-Hop Songs chart. Her follow-up album A Moment (1994) failed to make a commercial impact and ultimately released Hathaway from her recording contract with Virgin Records. In April 1999, she briefly re-emerged with her third album The Song Lives On, a collaborative album with musician Joe Sample. After another hiatus, Hathaway released her fourth album Outrun the Sky (2004). The album's lead single "Forever, for Always, for Love" peaked at number one on the US Adult R&B Songs chart. She later released two albums: Self Portrait (2008) and Where It All Begins (2011) on Stax Records.

In 2014, Hathaway's song "Something", featured on Snarky Puppy's album Family Dinner – Volume 1 (2013), won a Grammy Award for Best R&B Performance at the 56th Annual Grammy Awards. Her song "Jesus Children" secured a Grammy Award for Best Traditional R&B Performance at the 57th Annual Grammy Awards in 2015. In October 2015, she released a live album. The album spawn a cover version of Anita Baker's song "Angel", which became Hathaway's second number-one song on the US Adult R&B Songs chart. The success of the project garnered three Grammy Awards; including a Grammy Award for Best R&B Album, "Little Ghetto Boy" winning a Grammy Award for Best Traditional R&B Performance in 2015, and her rendition of "Angel" winning a Grammy Award for Best Traditional R&B Performance in 2016.
