Lasocin [laˈsɔt͡ɕin] is a village in the administrative district of Gmina Ożarów, within Opatów County, Świętokrzyskie Voivodeship, in south-central Poland.

Lasocin was granted Magdeburg rights by King Zygmunt August, upon request of Lasota, who named the town after himself.

In the late 16th century, the town became associated with the Polish Brethren, as the Lasota family, which owned Lasocin until 1592, promoted the Protestant Reformation.

Its residents mostly supported themselves as farmers, there also were some lumberjacks, who cut down trees for timber used by the Vistula river port at nearby Sulejow.

Following many other locations of northern Lesser Poland, Lasocin lost its town charter in 1869, as a reprisal of Russian authorities for the residents’ support of the January Uprising.
