From 1870 to 1903, more than 300 former members of the Third Michigan Infantry joined together for an annual reunion, which included a business meeting of their association, followed by a banquet. These reunions were held on the first Wednesday after the anniversary of the battle of Fredericksburg of December 13, 1862.

Beginning in 1904, annual association meetings fell on or near June 13, the day the regiment left Grand Rapids in 1861.

The 1885 reunion was held in Grand Rapids in conjunction with the reunion of the Society of the Army of the Cumberland, which was also held in Grand Rapids.

Although the records are unclear, the reunions in 1924, 1925 and 1926 were presumably held in Grand Rapids.

No reunions were held in 1873, 1875 or 1880.

The 55th and final reunion was held in Grand Rapids, Michigan in June of 1927; six members attended.
