Trochenbrod or Trohinbrod, also Sofievka or Polish Zofiówka (pl) ( – Sofiyevka, ), was an exclusively Jewish shtetl (a small town with a market) located in the Wołyń Voivodeship of the Second Polish Republic before World War II, with an area of . It was about northeast of Łuck in present-day western Ukraine. After the joint invasion of Poland in September 1939 by the Soviet Union and the Third Reich, the town was annexed for two years into the Ukrainian SSR by Joseph Stalin. However, it was completely eradicated in the course of the Nazi German Operation Barbarossa in 1941 and the remainder of the Holocaust. The nearest present-day villages are Yaromel (Яромель) and Klubochyn (Клубочин).
The settlement, inhabited entirely by Jews, was named after Sofia (hence Sofievka or Zofiówka), a Württemberg princess married to a future Tsar of Russia. She donated a parcel of land for the Jewish settlement in the Russian Partition following the destruction of the anti-Tsarist November Uprising against the Russian Empire.
