Armero, or Armero-Guayabal, is a municipality in the Tolima Department, Colombia. According to the National Department of Statistics of Colombia, 12,852 lived in the town in 2005. Its median temperature is 26 °C. It was founded in 1895, but was not officially recognized as the seat of the region until 29 September 1908, by President Rafael Reyes. The town was originally named San Lorenzo. In 1930, the name was changed to Armero in memory of José León Armero, a national martyr.

Because the region became the main cotton producer in the country, the city was called Colombia's White City. It was a prosperous agricultural area until 1985.

The original seat of the region was destroyed on November 13, 1985 after an eruption of the Nevado del Ruiz Volcano produced lahars that destroyed the town and killed about 23,000 people. Approximately 31,000 people lived in the area at the time. The incident became known as the Armero tragedy. While the destruction of the town made world news in its own right, the best known victim was Omayra Sánchez, a young girl who died after being trapped by water and concrete up to her neck for three days. After this event, the town of Guayabal was assigned as the seat of the municipality of Armero, rendering Armero a ghost town.
