The 1927–28 season was the 27th season of competitive football played by Cardiff City F.C. and the team's seventh consecutive season in the First Division of the Football League. The team were reigning holders of the FA Cup starting the campaign, having won the previous year's final. As a result, there were few significant changes in the playing squad from the previous season, with the club choosing to invest funds in their home ground Ninian Park. Despite being one of the lowest scoring sides in the league, Cardiff finished sixth in the First Division and were considered title contenders until late into the campaign when they suffered a poor run of form.
