The Grand Army of the Republic Memorial is a monument in Twin Springs Park of Siloam Springs, Arkansas.

Located in the southern part of the park, it consists of a concrete foundation, on which rest two tiers of granite slabs, laid horizontally.

The fourth side is engraved, from the top down, with an inverted five-point star labelled "GAR", then the words "IN GOD WE TRUST", then a Maltese cross engraved "WOMEN'S RELIEF CORPS 1833", then "ERECTED BY/CURTIS POST/1928", and finally a wreath topped by an eagle and crossed cannons, with "US" in the center surrounded by "PRESERVED BY THE GRACE OF GOD".
