Sąsiadka [sɔ̃ˈɕatka] is a village in the administrative district of Gmina Sułów, within Zamość County, Lublin Voivodeship, in eastern Poland.

Currently Sąsiadka is a small village, located at the edge of the Roztocze, but its history is very long, dating back to the early Middle Ages.

Next to contemporary village lies an ancient Slavic gord, which was one of the most important administrative centers of the so-called “Cherven Towns” (“Grody Czerwieńskie”), a historic region between Poland and Rus’.

The gord was most likely founded by Grand Prince Yaroslav the Wise, who built the fortified settlement in 1034 - 1039 to guard the border with Poland.

By that time the East - West trade route to Sandomierz which went through Sutiejsk had lost its importance, having been replaced by a different path from Kraków to Przemyśl and Lwów/Lviv in the 13th century.
