Robert McDowell McCracken (March 15, 1874 – May 16, 1934) was a United States Representative from Idaho.

Born in Vincennes, Indiana, McCracken was elected in 1914 as one of two at-large members from Idaho, representing the entire state alongside Addison T. Smith.

In 1916 he was defeated for reelection in the Republican primary by former congressman Burton L. French.

While campaigning for a return to Congress in 1934, McCracken died in an automobile accident near Emmett.

His vehicle went through a guard rail and tumbled down Freezeout Hill.
