Far too many to list in this forum. Nine major camps existed in Poland and there were nine in Germany. Seventeen camps were established in North Africa and most occupied countries also had camps. Camps can be divided into three types by purpose, Transit, Labor and Extermination. The best information source on the web is probably the Jewish Virtual Library. Between 1942 and early 1945 there were about 160 Nazi concentration camps.
Back in 1940, there were five concentration camps in Germany. These camps were established to eradicate resistance groups, political prisoners, racial groups of the Jews and Roma.

There were around 20,000 concentration camps and subcamps established by the Nazis throughout Eastern Europe during World War II. These camps were used for various purposes, including forced labor, mass executions, and extermination. Auschwitz-Birkenau, located in Poland, is one of the most notorious Nazi concentration camps.

The entirety of Europe. About half were killed in Poland, where many concentration camps were located.
Unfortunately, there were dozens upon dozens of death camps, or concentration camps as the Nazis preferred to call them. However, they were all centered in Germany and Poland. Poland was primarily where the camps were because that was basically 'Jew central'. It was also the first country in the war to be invaded and conquered.
The main concentration camps in Germany proper were Esterwegen, Neuengamme, Bergen-Belsen, Ravensbruck, Sachsenhausen, Mittelbau-Dora, Buchenwald, Flossenburg, Dachau, and Grafeneck. Note that while many, many deaths occurred in those camps, they were not built specifically as death camps (except for Grafeneck) - most of the death camps were in Eastern Europe, especially Poland and Czechoslovakia.
