Does anyone know why a hamburger is called that when there is no ham in it?

Same reason a Frankfurter is called that when there is no Frankfurt in it.

Hi Sam. As near as I know, sailors from Hamburg, Germany would want a quick meal at different places. They got a sandwich of chopped meat. The sandwiches subsequently came to be called "hamburgers" after the sailors.

The term hamburger originally derives from the German city of Hamburg[2], Germany's second largest city, from where many emigrated to America. In High German, "Burg" means "castle", earlier also city/town, and is a widespread component of city names. "Bürger" describes someone coming from that castle or town, (compare London -> Londoner), hence Hamburger can be a descriptive noun in German, referring to something from Hamburg. Similarly, frankfurter and wiener, names for other meat-based foods, are also used in German as descriptive nouns for people or things from the cities of Frankfurt and Wien (Vienna), respectively.

The term "ham" could derive from the word "hamme", a denomination for a moraine hillside[citation needed], although this remains unclear. The likeness to the English word "ham" is by pure chance (not to mention the fact that hamburgers do not contain ham).

The term "burger" became the synonym for many types of round sandwiches, although this word actually described a type of food rather than their creator(s) who allegedly originated in Hamburg.

It was created in Hamburg, Germany.

I guess it's because wherever something was originated from, it's what they end up calling it. For example, in science there's a law called Newton's 1st, 2nd and 3rd law right, because they originated from him. Another example, in gymnastics they make up new trick names according the girls who made it up.

i think its because it was created in Hamburg in Germany :)
