Christine Whelan Browne (born 6 August 1982) is an Australian performer who has worked extensively in musical theatre as an actress, dancer and singer.

[3][4] Whelan Browne acknowledged her teachers, "Susan Anne Walker and Rosie Harris for singing, I danced at Bev Palmer's for a couple of years when I was younger and more recently have been doing some TV and film courses around Melbourne and Sydney.

[8] Due to illness, Whelan missed the 18 July performance, and with no understudy available, Peter Cousens of Kookaburra Musical Theatre decided the production would continue with "key songs, scenes and dialogue" removed.

[17][18] Whelan appeared in The Drowsy Chaperone (January–February 2010) for Melbourne Theatre Company (MTC) as Janet van de Graaf,[3] for which she was a nominated for a Helpmann Award for Best Female Actor in a Musical.

[27] Other TV credits include Leila Esperance in Miss Fisher's Murder Mysteries (March 2012) and Katarina in Conspiracy 365 (December 2012).

[31] Cameron Woodhead of The Sydney Morning Herald felt despite the presence of Rush in the production, Whelan's "piping Gwendolyn steals the show, from the subtle subversions of her flirting behind her mother's back, to the ritualised cattiness of her scene with Cecily" (portrayed by Emily Barclay).

[31] She played Philia in the Melbourne season of A Funny Thing Happened on the Way to the Forum (October 2012) opposite Rush for which she was nominated for a Green Room Award for Best Supporting Actress.

[41] Her portrayal of Eileen Evergreen in The Production Company's Nice Work If You Can Get It (August 2015) was described by Katie Purvis of AussieTheatre.com as displaying, "considerable comic chops.

[45][46] Greg King's review of Spin Out determined, "[Whelan Browne and Lewis] are wasted in thankless roles as a couple of city slickers who rock up to the ute muster looking for a bit of excitement, and find themselves bemused by some of the bizarre rituals at play here.

[53] The actress joined the ensemble cast of the comedy news television program Shaun Micallef's Mad as Hell in 2019, and continued with the show in 2020 and 2021.

[54] In July of that year they performed together at The Production Company's The Producers, in which she played Ulla opposite Browne's Carmen Ghia.
