A hamdog is a combination of a hamburger and a hot dog. Dishes of this name have been invented in Australia and the United States.

Australian Mark Murray conceived one kind of hamdog in 2004. His version contains a beef patty cut in two, with a frankfurter placed in between the two patties, then topped off with cheese, pickles, sauces, tomato, lettuce and onion. He received a US design patent for the specially shaped bun in 2009.^[2]

Another variety of hamdog was invented in February 2005 by Chandler Goff, the owner of a bar in Decatur, Georgia. This version consists of a hot dog wrapped in a half pound of hamburger with bacon, cheese and onion on a hoagie bun which is deep-fried and served with a fried egg on top and a side of French fries.^[3] He started selling it at the Indiana State Fair in 2006.^[4] A hamdog eating contest was established in Vadnais Heights, Minnesota, in 2007 by Jimmy's Food and Drink. There is no reward for the winner other than bragging rights.^[5]

Dr. Nicholas Lang, professor of surgery at the University of Arkansas for Medical Sciences, advised against consuming a hamdog, even as a one-time snack.^[6]
