Joshua Miller (born April 17, 1954) is an American politician who serves as a Democratic member of the Rhode Island Senate representing Cranston District 28 since January 2007.

Miller graduated from Hope High School and attended the University of Rhode Island. Miller is Jewish.^[2]

In March 2014, Dan Bidondi of "Truthradio.com," a gun-rights activist and writer for the website Infowars, approached Miller with a microphone and camera in the Rhode Island State House rotunda during a hearing on gun legislation.^[13][14] Bidondi had previously gained attention for showing up at news conferences on the Boston Marathon bombing to yell out questions about whether the attack was a "false flag" operation.^[13] In the ensuing confrontation, Miller told Bidondi to "go fuck yourself."^[13][14] In a statement the following day, Miller apologized, stating that "regardless of the emotions and atmosphere of the moment, it does not justify the language I used that day. Out of respect for the decorum of the State House and the constituents I represent, I offer my apologies."^[14]

In 2023, Miller was arrested by Cranston police for malicious damage to an SUV displaying a "Biden sucks" bumper sticker, by keying the owner's car.^[15][16][17] Miller apologized for his language at the time and entered a plea of no contest to the misdemeanor charges. He was ordered to pay restitution to the victim, donate to the local food bank, and pay legal fees; upon satisfactorily finishing probation, after one year his offense will be expunged. Rhode Island Senate President Dominick J. Ruggerio declined to censure or punish Miller further after the court proceedings concluded.^[18][19]

Miller owns several Providence restaurants.^[16][19]
