Jacqueline Ellen Henderson (née Last; born 31 January 1975), better known as Jackie O, is an Australian radio and television presenter. She is best known for co-hosting The Kyle and Jackie O Show alongside Kyle Sandilands for twenty-one years. She has also presented The Hot Hits Live from LA, Hot30 Countdown, Take 40 Australia and two series of Australian Princess.

She has also hosted celebrity prank show Surprise Surprise Gotcha and appeared on the 2007 comedy series The Nation on the Nine Network. She was also the co-host of Big Brother (alongside Sandilands) after Gretel Killeen, the original host, resigned from the series.

On 1 November 2013, Jackie and Sandilands announced that they would not be returning in 2014 to host their 2Day FM breakfast show, which at that time was generating around $30 million AUD in advertising revenue yearly. On 29 November 2013, Kyle and Jackie O announced their move to rival radio network ARN and show on new 106.5 station in 2014.

On 3 March 2026, Jackie O quit The Kyle and Jackie O Show amid a feud between herself and Sandilands, ending a $200 million dollar contract with ARN radio after she told executives she "cannot continue to work with Mr Kyle Sandilands".
