Tovsto is a settlement in the Municipality of Laško in eastern Slovenia. It lies on the north side of Hum Hill, above the left bank of the Savinja River, just north of Laško. The area was traditionally part of the Styria region. It is now included with the rest of the municipality in the Savinja Statistical Region.
A small chapel-shrine, built at the source of a small stream in the settlement, dates to the 19th century.
