Denise Rebecca O'Sullivan (born 4 February 1994) is an Irish professional footballer who plays as a midfielder for Women's Super League club Liverpool and the Republic of Ireland national team.

Born in Cork, O'Sullivan joined the newly formed Cork City at the outset of the Women's National League (WNL) in 2011. She also played for Peamount United in their UEFA Women's Champions League campaigns. In 2013, she signed her first professional contract with Glasgow City and was named the Scottish Women's Premier League (SWPL) Players' Player of the Year in 2014. After a successful spell in Glasgow, she signed with the NWSL's Houston Dash in 2016, but was waived the following year.

O'Sullivan then joined the North Carolina Courage and was an integral player for the club as they won three NWSL Shields and two NWSL Championships in her first three seasons. She was voted most valuable player (MVP) by her Courage teammates in 2018 and 2019 – after both double-winning campaigns. She became the Courage's captain in 2023, also winning two NWSL Challenge Cups, and holds the club record for all-time appearances. She played on-loan with Canberra United and Western Sydney Wanderers in Australia and Brighton & Hove Albion in England during several NWSL offseasons. After nine years at North Carolina, she joined Liverpool in 2026.

O'Sullivan made her senior international debut for the Republic of Ireland at age 17 in 2011, since making over 100 appearances. She was named the FAI Senior International Player of the Year in 2015 and 2020. She was on the RTÉ Sports Person of the Year shortlist in 2019.
