The Major Indoor Soccer League (MISL), formerly known as the National Indoor Soccer League, is a professional indoor soccer league which began play in 2008. It is the third league to be known as the Major Indoor Soccer League. Originally, five teams had been announced to play in the inaugural season; four who were in the previous Major Indoor Soccer League and one formerly in the American Indoor Soccer League. However, the Orlando Sharks (formerly of the MISL) were forced to go inactive because of scheduling conflicts with Amway Arena. Later, the Massachusetts Twisters were brought in from the AISL to take the Sharks' place. The MISL is the top-tier professional indoor soccer league in the USA. 
The NISL was one of three leagues that organized in late 2008 after the demise of the second MISL; the other two being the PASL-Pro (an offshoot of the Premier Arena Soccer League) and the Xtreme Soccer League. The NISL and the XSL were more closely related, with both leagues first announcing four former MISL teams respectively and using the same game rules as the MISL.
In early July 2009, the XSL announced they were going on a one-year hiatus due to a lack of monetary backing which left the NISL as the highest indoor soccer league in the United States of America.
The NISL announced on July 13, 2009 that an all-star team of players from the Baltimore Blast, Rockford Rampage, and Philadelphia KiXX would play in a six-a-side outdoor exhibition match against an all-star team from Bermuda's Island Soccer League on July 19, 2009.
The NISL was attempting to get numerous teams from the folded XSL to join for the 2009–10 season, and succeeded in acquiring the Milwaukee Wave as a result. However, the Massachusetts Twisters would not return for 2009–10. The only former NISL team still playing in the MISL today is the Baltimore Blast. The rest of the 2010–11 season lineup would be made up of expansion teams, with the exception of the Wave.
Shortly before the league launched its 2009–10 season, the opportunity arose to purchase the rights to the "Major Indoor Soccer League" name; the league successfully acquired the rights and immediately rebranded itself as the newest MISL.
On July 18, 2010, the MISL played another All-Star Game against Bermuda's Island Soccer League. The Wave's Hewerton Moriera had 3 goals and 2 assists and the Philadelphia KiXX's Richardino added 2 goals and 2 assists in the MISL All-Stars' 8–3 win.
It was announced on August 18, 2010 that the MISL would expand into Missouri (Kansas City) and Omaha starting with the 2010–11 season.
An update to the official MISL "about" web page on October 6, 2010 acknowledged that the league was composed of only five teams, with the Rockford Rampage and Monterrey La Raza no longer active league members. On October 15, 2010, the Milwaukee Journal Sentinel reported the exodus of the Philadelphia KiXX and the addition of a Chicago franchise.
That year, the United Soccer Leagues (USL), which also oversees the men's USL Pro and USL Premier Development Leagues proposed a new league which was to begin play in the fall of 2011, the 'USL I-League.
On May 16, 2011, the USL, struggling to sign teams for the new league, agreed instead to take over operation of the MISL. Three teams from the proposed league, the Norfolk SharX, Rochester Lancers and Syracuse Silver Knights, were added.
On June 22, 2012, the MISL announced that a new Chicago franchise was awarded to Armando Gamboa and Dave Mokry for the 2012–13 season. The club was subsequently named the Chicago Soul, with the club making its home at the Sears Centre.
On June 25, 2012, The Norfolk SharX announced that the team would cease operations effective immediately because of financial difficulties.
A new incarnation of the St. Louis Ambush were announced as an expansion team on June 14, 2013. This is St. Louis' first professional indoor soccer team since the St. Louis Steamers folded in 2006.
