Samantha May Kerr (born 10 September 1993) is an Australian professional soccer player who plays as a striker for Women's Super League club Chelsea, and the Australia national team, which she has captained since 2019. Known for her speed, skill, and tenacity, Kerr is widely considered one of the best strikers in the world, and one of Australia's greatest athletes.

Kerr is the all-time leading Australian international scorer, with 73 international goals, and was the all-time leading scorer in the National Women's Soccer League (NWSL) in the United States until 2024. She is the only female soccer player to have won the Golden Boot in three different leagues and on three different continents—the W-League (Australia/New Zealand) in 2017–18 and 2018–19, the NWSL (North America) in 2017, 2018, and 2019, and the Women's Super League (Europe) in 2020–21 and 2021–22.

Kerr started her career at the age of 15 with Perth Glory where she played from 2008 to 2012, before moving to Sydney FC. In 2013, she joined the Western New York Flash for the inaugural season of the NWSL and helped lead the team to win the NWSL Shield. She later played for Sky Blue FC and the Chicago Red Stars in the same league. In 2019, Kerr indicated her interest to play in Europe, and having fielded multiple offers from clubs such as Olympique Lyonnais, Kerr ultimately signed with Chelsea, so far winning 8 trophies with the club, including back-to-back-to-back Women's Super League titles, as well as helping the team reach the UEFA Women's Champions League final for the first time in 2021.

Kerr earned her first senior international cap in 2009 at the age of 15 and has since represented Australia at the 2010, 2014, 2018, and 2022 AFC Asian Cup tournaments, the 2011, 2015, 2019, and 2023 FIFA World Cups, and the 2016 and 2020 Summer Olympics. During the 2019 World Cup, she became the first Australian player to score a hat-trick at a World Cup tournament. In 2021, she captained the team to their historic first ever semi-final of a major tournament during the delayed 2020 Summer Olympics, resulting in their best ever fourth-place finish.

Kerr was born in East Fremantle, a suburb of Perth, Western Australia. She is the daughter of Roxanne (née Regan) and Roger Kerr. Her father, a professional Australian rules football player, was born in Calcutta to an English father (a featherweight boxer) and an Indian mother who played basketball. Her mother also comes from a sporting family: her father Harry and uncle Con Regan were professional footballers in the West Australian Football League and another uncle J. J. Miller was a champion jockey who won the Melbourne Cup in 1966 with Galilee.

I started at 12. Before that it was all AFL. I hated soccer when I was a kid. I never had a soccer ball around the house.

Kerr played Australian rules football when she was young. Both her father and older brother, Daniel Kerr, were professional Australian rules footballers. She played the sport until switching to association football at the age of 12, mostly due to gender restrictions.

Kerr attended Samson Primary School and Somerville Baptist College. Despite facing some struggles transitioning from Australian rules football to association football, at age 13, she was spotted by Perth Glory striker Bobby Despotovski who described her athleticism and raw talent as "exceptional". At age 15, she made her W-League and international debuts.
