1886–87 Dumbarton F.C. season

The 1886–87 season was the 14th Scottish football season in which Dumbarton competed at a national level.

Scottish Cup
Dumbarton reached their fourth Scottish Cup final full of confidence, especially having defeated Queen's Park in the semi-final, but it wasn't to be and Dumbarton lost out to the East of Scotland Shield holders Hibernian by the odd goal in three.

Dumbartonshire Cup
Dumbarton met their old rivals Renton in the third round and found them to be too good on the day.

Glasgow Charity Cup
It was much the same story in the Glasgow Charity Cup, where Dumbarton fell at the first hurdle to Queen's Park.

Friendlies
During the season, 28 'friendly' matches were played, including home and away ties against Rangers and 3rd LRV, matches against Lanarkshire Cup holders, Airdrie and Renfrewshire Cup holders, Abercorn and a two match north of Scotland tour in the New Year Holidays. In addition, four matches were played against English opposition, including a north of England tour during Easter. In all, 9 were won, 7 drawn and 12 lost, scoring 61 goals and conceding 62.

Player statistics
Of note amongst those donning the club's colours for the first time were John Madden and William Robertson. At the same time 5-time internationalist Michael Paton was lost from the club's squad.
