Kilwinning Rangers were originally formed as a Juvenile football club in 1899, sharing Blacklands Park with the local senior club - the now defunct Kilwinning Eglinton. In 1902 the club joined the Junior grade however it was three years before the club won their first honour, emerging as winners of the Ayrshire Junior Challenge Cup in 1904–05.
They became the first Ayrshire club to win the Scottish Junior Cup in 1908–09 with a 1–0 victory over Strathclyde A second appearance in the final followed in 1909–10, however Kilwinning were defeated 3–0 by Ashfield. Ninety years later, Kilwinning regained the Scottish Junior Cup with a 1–0 victory over Kelty Hearts, in a season which saw them win six out of the seven trophies available to them.
Kilwinning became the first Ayrshire side to win the West Super League in 2003–04 however financial issues resulted in the team finishing bottom of the league the following season and subsequently relegated. Most of the following decade was spent in the Ayrshire District League with a promotion to the Super First Division achieved in 2012–13. The following season almost resulted in Kilwinning avoiding relegation, however the club had fielded an ineligible player for twelve matches and the resulting nineteen point deduction relegated the side to the bottom division.
A change in management occurred in February 2014 with the appointment of Chris Strain and Colin Stewart, although Stewart left to take up a coaching role at Rangers in 2015 and Strain assumed the role of sole manager.
Kilwinning achieved successive promotions in 2014-15 and 2016–17, courtesy of a play-off victory against Shettleston and maintained their top flight status the following season by defeating Kilsyth Rangers in another play-off.
In 2020, Kilwinning applied to join the newly formed West of Scotland Football League, which would see them leave the Junior leagues after joining 118 years prior The following year, Kilwinning began their application to join the Scottish Football Association. This application was successful in June 2022, allowing the Buffs to participate in the Scottish Cup for the first time in the history in the 2022–23 season.
In early April 2022, Chris Strain was sacked. Former player and ex-professional, Mark Campbell was appointed caretaker manager until the end of the season. Broomhill manager David Gormley was hired for the start of the next season. In January 2023 Gormley was relieved of his position as manager and former Clyde, Ayr United, Morton and Stirling Albion player Chris Aitken was appointed as manager in early February. Following Aitken's resignation, Ex-Caledonian Locomotives boss Kevin Kelly was appointed along with his assistant Steven Saunders.
