Michael Aloysius Feighan (February 16, 1905 – March 19, 1992) was an American Politician from Lakewood, Ohio, near Cleveland. He served as a member of the Ohio House of Representatives, and as a Democratic Party U.S. Representative from 1943 to 1971, serving Ohio's 20th congressional district.

During the legislation of the Immigration and Nationality Act of 1965 Feighan insisted that "family unification" should take priority in immigration policy over "employability", on the premise that such a weighting would maintain the existing ethnic profile of the country. That change instead resulted in chain migration dominating the subsequent patterns of immigration to the United States and consequently a more ethnically diverse population.

After Feighan had served almost three decades in the House of Representatives, some local Democratic officials, led by Cleveland City Council President James V. Stanton, had grown tired of his leadership. Sensing that they could not beat Feighan in one election, they set up a stalking horse running a Michael Sweeney, a local Lawyer with a good political name. Sweeney lost, but his vote total showed that Feighan could be vulnerable in a rematch. Two years later, in 1970, Stanton himself ran and defeated Feighan in the Democratic primary, concluding Feighan's political career.
