David O'Byrne (born 17 March 1969) is an Australian trade unionist and politician. A prominent union leader prior to entering politics and the brother of fellow politician Michelle O'Byrne, he has been an Independent member of the Tasmanian House of Assembly since 2024, after previously serving as a Labor Party member from 2010 to 2014 and from 2018 to 2024, representing the electorate of Franklin.

In 2018 O'Byrne was re-elected to the House of Assembly with a strong personal vote, topping the Labor ticket. In May 2021, he was re-elected. In June 2021, O'Byrne replaced Rebecca White as the leader of the Tasmanian Labor Party, winning 74 percent of the vote as against 26 percent for the right-aligned Braddon MP Shane Broad.

In July 2021, O’Byrne resigned the leadership following an allegation of sexual harassment levelled against him by a former union staffer, relating to alleged events in 2007 and 2008.

An independent investigation conducted by Barbara Deegan, a commissioner of the Commonwealth industrial tribunals from 1996 to 2014, found that his actions were "inappropriate" and “wrong”, but did not constitute sexual harassment. No further action was taken, but O'Byrne resigned from the leadership nonetheless, and Rebecca White was elected to succeed him.

From August 2021, O'Byrne sat on the crossbench as an Independent Labor member, until resigning his Labor membership after Labor leader Rebecca White vetoed his preselection. He announced his candidacy as an Independent on 4 February 2024.

In the 2024 Tasmanian State Election, O'Byrne received a strong personal vote and was re-elected with the highest primary vote of any independent candidate.
