2015 National Women's Soccer League season

The 2015 National Women's Soccer League season was the third season of the National Women's Soccer League, the top division of women's soccer in the United States. Including the NWSL's two professional predecessors, Women's Professional Soccer (2009–2011) and the Women's United Soccer Association (2001–2003), it was the ninth overall season of FIFA and USSF-sanctioned top division women's soccer in the United States. The league was operated by the United States Soccer Federation and received major financial backing from that body. Further financial backing was provided by the Canadian Soccer Association and the Mexican Football Federation. All three national federations paid the league salaries of many of their respective national team members in an effort to nurture talent in those nations.

In January, Jeff Plush was named NWSL commissioner, replacing Cheryl Bailey.

To accommodate the 2015 FIFA Women's World Cup, the league announced it would take a two-week break from June 7–19, reduce the season to 20 games, and extend the playing calendar into September.

For the second straight season, FC Kansas City defeated the NWSL Shield winners Seattle Reign FC 1–0 to win the NWSL championship.

Tiebreakers
The initial determining factor for a team's position in the standings is most points earned, with three points earned for a win, one point for a draw, and zero points for a loss. If two or more teams tie in point total, when determining rank and playoff qualification and seeding, the NWSL uses the following tiebreaker rules, going down the list until all teams are ranked.

If two teams tie:


 * 1) Head-to-head win–loss record between the two teams.
 * 2) Greater goal difference across the entire season (against all teams, not just tied teams).
 * 3) Greatest total number of goals scored (against all teams).
 * 4) Apply #1–3 to games played on the road.
 * 5) Apply #1–3 to games played at home.
 * 6) If teams are still equal, ranking will be determined by a coin toss.

If three or more teams tie, the following rules apply until only two teams remain tied, at which point the two-team tiebreakers listed above are used:


 * 1) Points per game against all other tied teams (total all points earned in games against tied teams and divide by games played against tied teams).
 * 2) Greater goal difference across the entire season (against all teams, not just tied teams).
