The Professors: The 101 Most Dangerous Academics in America is a 2006 book authored by conservative activist David Horowitz, published by Regnery Publishing. The book argues that many academics in American universities hold anti-American views and are sympathetic to terrorists and non-democratic regimes, listing 101 professors as examples of those allegedly poisoning the minds of students with radical left-wing ideologies. Horowitz, a former New Left activist turned conservative, uses the book to critique what he sees as a pervasive bias in higher education, calling for greater ideological diversity on campuses. It became a bestseller in conservative circles, sparking debates about academic freedom and political correctness.

The book has been highly controversial, criticized by academics and organizations like the American Association of University Professors (AAUP) for promoting McCarthy-like witch hunts, containing factual errors, and potentially defaming individuals without due process. Several profiled professors publicly responded, accusing Horowitz of cherry-picking quotes and misrepresenting their work. Despite the backlash, it influenced conservative discourse on education and led to Horowitz's 'Academic Bill of Rights' campaign. No major legal actions directly stemming from the book are documented, but it contributed to ongoing tensions between conservative activists and academia.

As a publication, The Professors exemplifies Horowitz's broader efforts to expose perceived liberal biases in institutions, building on his previous works like 'Radical Son.' It remains a reference point in discussions of campus politics, though its claims are often disputed by scholars who view it as partisan propaganda rather than objective analysis.
