Lyubcha Castle or Lubcz Castle was a residential castle of the Radziwill family on the left bank of the Neman River at Lyubcha near Novogrudok, Belarus.
The castle began its life in 1581 as a fortified residence of Jan Kiszka, a powerful Calvinist magnate. It had timber walls and a single stone tower, and was surrounded by moats on three sides, the fourth side protected by the river.
Lyubcha later passed to Janusz Radziwiłł, Great Hetman of Lithuania, who expanded the castle by adding three stone towers. In 1655, it was taken and devastated by the rebellious Cossacks under Ivan Zolotarenko.
