Anneke van Giersbergen (born 8 March 1973) is the former lead singer of the Dutch heavy metal band The Gathering, now involved in a solo project called Agua de Annique. She has also worked with Lawn, Farmer Boys, Ayreon, Napalm Death, Moonspell, Globus, Giant Squid, Devin Townsend and Within Temptation.

Van Giersbergen was born in Sint Michielsgestel, Netherlands. By the age of 8, she participated in soundmix contests and at age 12 joined her school choir and later joined her first rock band.

She played with several bands before becoming part of the duo Bad Breath who played a mix of blues, jazz, folk and funk. She joined heavy metal band The Gathering in 1994, and she is most notable for her work with them.

In 1998, she sang on the Ayreon album Into the Electric Castle, a concept album telling the tale of an alien entity 'kidnapping' 8 human souls from different times. Anneke portrayed an Egyptian woman from the time of the pharaohs.

She appears on the album Rubicon from John Wetton and Geoffrey Downes on the tracks "To Catch a Thief" and "Tears of Joy".

She also appears on the 2006 album Smear Campaign by the grindcore/death metal band Napalm Death, on the tracks "Weltschmerz" and "In Deference," contributing spoken rather than sung vocals "for good effect and relevance to the track."

Anneke's musical roots are in the classical and jazz music, but she enjoys rock and pop the most. Her main influences are Prince, Ella Fitzgerald and Thom Yorke (Radiohead).
