The Top 50 Medical Journals with Impact Factor and Weekly Readership

Written By Nicola Donelan

This Top 50 Medical Journals list ranks the world’s most influential academic and clinical journals by their Impact Factor, the standard metric reflecting how often a journal’s articles are cited each year. High impact factors signal journals with significant influence in medicine, healthcare, and scientific research.

Each entry in the Top 50 highlights the journal’s specialty, most recent impact factor, readership reach, and a direct link to its official website. Whether you are a researcher preparing a manuscript, a clinician seeking trusted evidence, or a healthcare professional staying current, this list serves as a practical guide to the most influential and widely read journals in medicine.

Also explore the Top 25 Journals for Oncology, the Top 25 Neurology Journals, the Top 25 Cardiology Journals by impact factor and influence, or the Top 25 Easiest High-Impact Medical Journals to Publish In.
