The 1934–35 season was the 58th Scottish football season in which Dumbarton competed at national level, entering the Scottish Football League and the Scottish Cup. In addition Dumbarton competed in the Dumbartonshire Cup.
See main article: 1934–35 Scottish Football League. After the optimism of the previous season, Dumbarton's 13th season in a row in the Second Division was to prove unlucky as they slumped to finish 16th out of 18, with 22 points - 30 behind champions Third Lanark.[1] During the season, a number of big defeats were suffered, conceding a 9, an 8 and 6 goals twice.
See main article: 1934–35 Scottish Cup. This season it was a second round exit, to First Division St Johnstone.
Dumbarton failed to regain the Dumbartonshire Cup, with amateur side Vale Ocaba retaining the trophy. Both games were held over until the start of the 1935–36 season.
