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.

That year, he and Edith Ajello held a press conference to announce that they would introduce a bill to legalize, tax, and regulate marijuana similarly to alcohol.

[12] 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.

Rhode Island Senate President Dominick J. Ruggerio declined to censure or punish Miller further after the court proceedings concluded.
