Arthur Hornbui Bell (February 14, 1891 – March 1, 1973) was an attorney and the Grand Dragon of the Ku Klux Klan in New Jersey.

[1] After attempting to collaborate with the pro-Nazi German American Bund, Bell and Imperial Kaliff Alton Milford Young were both kicked out of the Klan.

[6] Arthur Bell is known to have been a member of the "Over There" theatre organized under Benjamin Franklin Keith and visited Belgium, England, France, and the Netherlands.

[9][10][11] In 1925 he wrote the introduction to Alma White's pro-Klan book The Ku Klux Klan in Prophecy: This book brings out vividly the titanic struggle now taking place, not only in the United States, but over the entire world, and while at the present time the battle raging has not reached the point where bullets, swords and poison gas are the reasons used, the time will soon arrive when the Roman Catholic craving for world-power will, if not checked, cause a revival of a religious war that will be far more disastrous than the late World War.

Imperial Kaliff Alton Milford Young was also removed from the Klan and the meeting was reported by Colescott to Martin Dies.
