Emma Kay Checker (born 11 March 1996) is an Australian soccer player who plays as a defender for Umeå IK. She has represented Australia at under-17, under-20 and senior levels. She made her senior international debut for Australia in November 2012 at the age of 16.
Checker made her senior debut for Adelaide United on the opening day of the 2011–12 W-League season, aged 15.  She went on to make six further appearances for the club that season, and played in Adelaide's first W-League victory in 34 matches;   Checker was one of eight players retained by Adelaide United for the 2012–13 season,  and went on to make eleven appearances that season.  On 31 May 2013, she became the first female in nearly 20 years to play in an under-18s match with men, when she represented West Torrens Birkalla against White City. 
Prior to the start of the 2013–14 season, Checker switched to Melbourne Victory.  She made her debut for the side on 16 November; despite scoring the opening goal of the game after four minutes, she was unable to prevent Melbourne from slipping to a 5–1 defeat against Sydney.  She won her first Championship against Brisbane Roar in the 2014 W-League Grand Final.
In September 2015, Checker joined Canberra United.  On 5 January 2016, she suffered an ACL injury and was ruled out for the rest of the season.  She returned from injury for the following season on 28 December 2016 against Melbourne Victory  and went on to be part of the 2016–17 W-League premiership winning team.
In 2017, during the W-League off-season Checker played with Incheon Hyundai Steel Red Angels in South Korea before a knee injury interrupted her spell. 
On 22 September 2017, Checker returned to Adelaide United, signing a two-year contract.  She made history by becoming the youngest captain of a W-League team during her stint at Adelaide.  She went on and reasserted herself as one of the country's strongest and most reliable defenders over the past two seasons. She sits fourth on Adelaide's all-time appearance list with 41 games. 
On 19 September 2019, Checker signed with Melbourne City ahead of the 2019-20 W-League season.  She went on to win both the Premiership and Championship, having made 14 appearances across the campaign and was a key part of a defence that conceded just five goals for the season.
On 22 December 2020, Checker resigned with Melbourne City for the 2020-21 W-League season.  She was appointed captain ahead of the upcoming season.  After four months on the sideline, she returned from injury in Round 4 against Melbourne Victory. In Round 5, she scored her second ever W-League goal against her former side Adelaide United.
In August 2021, Checker re-signed with Melbourne City for two more years and confirmed she will remain captain. 
On 15 June 2020, Checker became the latest player to head to Europe, signing with French club FC Fleury 91 on a two-year contract.  She made her Division 1 Féminine debut against Issy on 26 September 2020. During her second overseas stint, she suffered a stress fracture in her fibular, cutting short her time in France. 
In April 2021, Checker signed with Selfoss of the Icelandic Úrvalsdeild kvenna. 
Prior to making her Adelaide United debut, Checker made her debut for Australia's under-17 team in a friendly against New Zealand.  She was part of her country's unsuccessful attempt to qualify for the 2012 FIFA U-17 Women's World Cup, and her performances earned her a place in Australia's senior training camp in March 2012.  Still aged 16, she was selected for a friendly against New Zealand on 24 June 2012, but remained an unused substitute.  Instead, she made her senior international debut on 23 November 2012, playing the entire match in a 4–0 victory over Hong Kong. 
In September 2019, after an impressive season with Adelaide United, Checker was called up to Australia's senior training camp in preparation for their upcoming friendlies against Chile. In November 2019, she came on as a substitute for both matches against Chile. 
Checker is currently studying a Bachelor of Business at Deakin University.
