Sally Whitwell (born 1974) is an Australian classical music pianist, composer, arranger, conductor and teacher. She has released five solo albums all on the ABC Classics record label. The first three albums peaked in the top 5 on the ARIA Charts' Classical Albums.

At the ARIA Music Awards of 2011 Whitwell won the Best Classical Album award for Mad Rush: Piano Music of Philip Glass. In 2012 she was nominated in the same category for The Good, the Bad and the Awkward. She won the same category in 2013 for All Imperfect Things: Solo Piano Music of Michael Nyman. Virginia Read won Engineer of the Year for that album and was also nominated for Producer of the Year.

Whitwell was born in 1974 and grew up in Canberra. She learned to play the piano on her grandmother's "imposing beast of an instrument", including "Cockles and Mussels" and "Wedding of the Painted Doll". In the 1980s she had piano lessons where "a classical tuition is what you would receive". She also studied bassoon but from the age of 16, she concentrated on the piano.

Whitwell attended Canberra Girls' Grammar School, then the Australian National University's School of Music and completed a Bachelor of Music with Honours in 1997. She completed further studies at Sydney Conservatorium of Music for a graduate diploma in accompaniment. During her time at university she also worked part-time, both as a solo performer on the cabaret circuit and as part of ensembles.

During the 2000s Whitwell provided session work for the Australian Broadcasting Corporation (ABC), whenever they wanted "something slightly left-field, or crossover, or contemporary". By 2004 Whitwell provided piano for The Elizabethan Sydney Orchestra and their performance was included on an album for ABC Classics, Felix and Me: Musical Highlights from ABC Classic FM Breakfast. In the following year she was one of the contributors to The Classic 100 Piano, a set of eight CDs, with piano-based tracks selected by listeners to ABC Classic FM. Whitwell arranged some tracks and provided accompaniment of Teddy Tahu Rhodes' and David Hobson's 2009 album You'll Never Walk Alone.

In 2009 she contributed Spiegel im Spiegel, with Sally Maer on cello, for the soundtrack to ABC-TV documentary special, Bombora – The Story of Australian Surfing, which describes a history of the sport and the 1963 instrumental single "Bombora", by The Atlantics. In 2010 Whitwell released "Roadtrip", a self-composed score for flute and piano. She was inspired by "the train commute I make weekly from Sydney to a university teaching job in Newcastle".

For three days in November 2010, Whitwell worked at the ABC's studios to record her debut solo album, Mad Rush: Piano Music of Philip Glass, which was issued on 3 June 2011 by ABC Classics. For the album she utilised a 102-note piano crafted by Australian company, Stuart & Sons. Melissa Lesnie of Limelight noted in August that the album of works written by minimalist composer, Philip Glass, had become a "surprise hit, not least thanks to Glass's broad appeal across genre and age divides". Whitwell told Lesnie that the Stuart & Sons piano "allows so many colours, such subtle gradations of dynamics, that you can't get on another instrument in my experience. A Stuart sound is like crystal, yet it's very flexible".

At the ARIA Music Awards of 2011 Whitwell won the Best Classical Album award for her debut album. In December The Australian's Mark Coughlan described her interpretation as "excellent throughout this disc, going beyond mere notational accuracy to breathe life and shape into the music". Stephen Eddins writing for AllMusic declared "[her] disregard for conventionality bubbles through just about every aspect of her recording ... surprising rhythmic emphases may make anyone familiar with the piece sit up and do a double-take, and her tempo is about 25% faster than Glass' version ... [s]he brings acute intelligence and sensitive musicality to each of the pieces, most of which have a delicately melancholy tone".
