Concepción (Spanish pronunciation: [konseβˈsjon]) is a municipality in the Sololá department of Guatemala.

After the Spanish conquest of Guatemala the town was called "Nuestra Señora de La Concepción" after the Our Lady of the Immaculate Conception.

During the Spanish Colony it was part of the Tecpán Atitlán district and when Tecpán became an "alcaldía mayor" (English:Major municipality) of Sololá Nuestra Señora de La Concepción became part of it, as reported in 1749.

Documents from 1765 show its name as "Nuestra Señora de la Concepción Pajixolá".

And in 1770, archbishop Pedro Cortés y Larraz described the town as "Concepción Kixalá, part of San Francisco Panajachel parish".
