Richard Juien-Dah Pan (Chinese: 潘君達; born October 28, 1965) is an American Democratic politician and physician who served in the California State Senate from 2014 to 2022, representing the 6th Senate district, which encompassed parts of Sacramento and Yolo counties.

Pan was born to a Taiwanese American immigrant family in Yonkers, New York.

[3] Dr. Pan was a professor at the University of California, Davis where he led the pediatric residency program and founded Communities and Physicians Together, a service learning curriculum that placed physicians-in-training with community settings to learn about social determinants of health.

Pan was Chair of the California Asian American & Pacific Islander Legislative Caucus from 2020-2022.[when?]

In 2021 he authored a law (SB 742) that makes illegal to "harass, intimidate, injure or obstruct" people who are on their way to get a vaccination; the law was inspired by an incident in January when protesters targeted and briefly shut down a mass vaccination site in Los Angeles.
