Louis Charles Rabaut (December 5, 1886 – November 12, 1961) was an American lawyer and politician from the U.S. state of Michigan.

In 1934, Rabaut defeated incumbent Carl M. Weideman in the Democratic primary elections for the Michigan's 14th district to the U.S. House of Representatives.

If we deny to the Government the authority to roll back prices and maintain firm economic controls, we are sure to be remembered.

"[2] On April 20, 1953, prompted by a letter from Brooklyn resident H. Joseph Mahoney, Rabaut submitted a resolution to amend the Pledge of Allegiance with the words "under God".

Rabaut's bill was the first of many similar efforts, culminating in Representative Charles Oakman and Senator Homer Ferguson's joint resolution in 1954.

Speaking in support of the bill, Rabaut said: You may argue from dawn to dusk about differing political, economic, and social systems, but the fundamental issue which is the unbridgeable gap between America and Communist Russia is a belief in Almighty God.
