Brownsboro was first settled in 1849 by John "Red" Brown, who operated a toll bridge across Kickapoo Creek on the road to Jordan's Saline and Tyler.

It was established in 1845 by Johan Reinert Reiersen of Kristiansand, Norway, who urged Norwegian immigrants to settle in the new community.

According to the United States Census Bureau, Brownsboro has a total area of 2.4 square miles (6.1 km2), all land.
