This list of Nobel laureates affiliated with Columbia University as alumni or faculty comprehensively shows alumni (graduates and attendees) or faculty members (professors of various ranks, researchers, and visiting lecturers or professors) affiliated with Columbia University in New York City who were awarded the Nobel Prize or the Nobel Memorial Prize in Economic Sciences. People who have given public lectures, talks or non-curricular seminars; studied as non-degree students; received honorary degrees; or served as administrative staff at the university are excluded from the list. Summer school attendees and visitors are generally excluded from the list, since summer terms are not part of formal academic years; the same rule applies to the extension school.

Alumni or faculty members of Barnard College after 1900 and Bard College by 1944 are included in the list.^[1][2] Physicians and long-term medical staff of the Mary Imogene Bassett Hospital are included in the list.^[3][4]

The Nobel Prizes, established by the 1895 will of Alfred Nobel, are awarded to individuals who make outstanding contributions in the fields of Chemistry, Literature, Peace, Physics, and Physiology or Medicine.^[5] An associated prize, the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel (commonly known as the Nobel Prize in Economics), was instituted by Sweden's central bank, Sveriges Riksbank, in 1968 and was first awarded in 1969.^[6]

As of the 2023 awards, 103 Nobel laureates have been affiliated with Columbia University as alumni or faculty. Among the 103 laureates, 72 are Nobel laureates in natural sciences;^{[lower-alpha 1]} 46 are Columbia alumni (graduates and attendees) and 34 have been long-term academic members of the Columbia faculty; and subject-wise, 33 laureates have won the Nobel Prize in Physics, more than any other subject. This list considers Nobel laureates as equal individuals and does not consider their various prize shares or if they received the prize more than once.

Affiliates during the Manhattan Project, the scientific research project which developed the first nuclear weapons, who specifically worked for the military are also excluded from this list.
