Was there a treaty ending world war 2 in Europe?

Yes, there were several treaties that effectively ended World War II in Europe. The most notable one is the Treaty on the Final Settlement with Respect to Germany, commonly known as the Treaty of Berlin, which was signed on September 12, 1990. This treaty formally ended World War II in Europe and paved the way for German reunification. However, the initial formal end of hostilities in Europe came with the unconditional surrender of Nazi Germany on May 8, 1945, commonly known as Victory in Europe (VE) Day.
