Several prominent celebrities have publicly expressed their disapproval following President Donald Trump's second inauguration. These reactions unfolded primarily on social media platforms like Bluesky Social and X.

Legendary singer and actress Barbra Streisand criticized Trump's return to office, comparing his previous term to a "bad reality show" and suggesting the current one was starting off even worse. She also targeted Trump's merchandise sales and cabinet appointments, questioning the latter's qualifications and emphasizing their perceived loyalty over experience. Streisand further criticized an executive order regarding citizenship, expressing hope that the Supreme Court would overturn it.

Actor Jon Cryer referred to the commencement of Trump's presidency as the beginning of "America’s criminal presidency." "Star Trek" actor George Takei used the term "plutokleptokakistocracy" to describe the situation, criticizing the influence of the wealthy and what he viewed as inept governance. He later added, "Elect a clown, expect a circus. Elect a criminal, expect crimes."

Author Stephen King focused on the demographics of the inauguration attendees, noting the prevalence of white, wealthy men and the absence of what he considered Trump's core supporters. Actor John Cusack discouraged viewers from watching the inauguration, calling it a "snuff film" and "totally meaningless." Rapper Ice T questioned the relevance of felony convictions on job applications given a felon's ability to become president.
