Ana Lynch (born August 14, 1974), known by her stage name Ana Matronic, is an American singer, best known as the female co-lead vocalist for Scissor Sisters.

She joined Scissor Sisters, founded by Jake Shears and Babydaddy, after they played their first live gig at club Knockoff on the Lower East Side of Manhattan.

She has stated that in her eyes, the objective of the band is "about people displaying their fantasies on the outside, trying to break out of the everyday, and look like their dreams." In The Scissorhood, the fan community for the Scissor Sisters, those fans who hold a special affinity for Ana are known as "nuns". Homosexual men and heterosexual women who are attracted to Ana term themselves "Anasexual".

In 2005, she was featured on the New Order single, "Jetstream". The single was taken from the band's album, Waiting for the Sirens' Call. In 2009, Matronic performed on the glass harmonica at the New Museum in NYC in Auroville, a multimedia ritual tribute to an experimental community dedicated to the guru Sri Aurobindo. Ana appears as a guest vocalist on the Mark Ronson produced track 'Safe (In the Heat of the Moment)' from the December 21, 2010, release All You Need Is Now from the band Duran Duran.

In 2012, Matronic appeared as an advisor on The Voice UK, pairing up to assist Jessie J. The following year, she served as commentator of the BBC Three broadcast of the Eurovision Song Contest 2013 semi-finals in Malmö, Sweden for the United Kingdom, replacing Sara Cox who had commentated previously. Matronic returned in 2014 as radio commentator on Radio 2 Eurovision, a pop-up DAB station, for the second semi-final of the Eurovision Song Contest 2014 in Copenhagen, Denmark.

Matronic appeared on Strictly Come Dancing: It Takes Two on 15 November 2013, alongside Jason Donovan and Jodie Prenger.

She currently presents a weekly show on BBC Radio 2 titled Disco Devotion from 12 till 2 am on Saturday nights/Sunday mornings, on air since April 2017. From 24–27 July 2017, she covered for Jo Whiley and presented a special program alongside Scott Mills on 29 July celebrating the 50 year anniversary of the decriminalisation of male homosexual activity in the UK. She performed a live DJ set at Radio 2 Live in Hyde Park on 10 September and will host the New Year's Eve show.
