Season 2000–01 was the 117th football season in which Dumbarton competed at a Scottish national level, entering the Scottish Football League for the 95th time, the Scottish Cup for the 106th time, the Scottish League Cup for the 54th time and the Scottish Challenge Cup for the 10th time.
At the start of season 2000-01 Dumbarton would be without a home until their new stadium was ready - and would play their 'home' games 40 miles away at Coatbridge, the home of Albion Rovers. The spell at Cliftonhill was not successful as only one 'home' game there was won - and by that time any chance of promotion had been lost. At the beginning of November manager Jimmy Brown left the club to be replaced by his assistant Tom Carson.
The big day of the opening of the new home ground was 2 December. A game between two of the bottom clubs in Division 3 would not normally have attracted a large turnout but as it was, an almost capacity crowd watched Dumbarton beat Elgin City 3-0. Results post-move did improve and in the end a mid-table 6th-place finish was achieved.
In the national cup competitions, there was some progress in all. In the Scottish Cup, Dumbarton defeated East Stirling in the first round, after a drawn match, but disappointingly lost in the next round to Stranraer.
In the League Cup, after an exciting penalties win over Ayr United, Dumbarton lost out to Livingston in the second round.
Finally, in the Scottish Challenge Cup, after nine unsuccessful attempts, Dumbarton finally won a first round tie - against Elgin City, but the optimism was short-lived as Arbroath would win the second round match-up.
Locally, in the Stirlingshire Cup, Dumbarton won one and lost one of their two group ties, and failed to progress.
