Adam Galloway Miller (21 October 1887 – 1972) was a Scottish footballer who played as a left back, primarily for Hamilton Academical.
He played in the 1911 Scottish Cup Final which Accies lost to Celtic after a replay. He also played in the Scottish Football League for St Mirren and Johnstone. At representative level, he was selected for Lanarkshire at both junior and senior grades, and was twice a reserve for the Scottish Football League XI.
Miller had three brothers who were also footballers, all playing for Hamilton Academical at some point: William had a short career, but John had productive spells with Aberdeen and Partick Thistle, while Tom was a regular with Liverpool and was capped three times for Scotland.
