Thomas Robb (born October 13, 1946) is an American white supremacist, Imperial Wizard of the Ku Klux Klan and Christian Identity pastor.

He also decided to accept members via mail-in forms, rather than through initiation rites that had been common Klan practice in the past.

[5] Robb has maintained his ties with other far-right groups; he has spoken at the Aryan Nations' annual "World Congress" of hate group leaders, he has appeared on Jamie Kelso's white supremacist Voice of Reason Radio Network, and he has regularly contributed to the white supremacist Internet forum website Stormfront.

[2] In 1999 Robb was interviewed separately by British journalists Louis Theroux and Jon Ronson, and featured in documentaries produced by both.

[8] In May 2022, British YouTuber Niko Omilana published a video in which he described his experiences in Zinc and Harrison while he disguised himself as a journalist for the BBC.
