"Sitalā Māju" (Nepal Bhasa: 𑐳𑐶𑐟𑐮𑐵 𑐩𑐵𑐖𑐸) is a traditional Nepalese song based on an historical event, and recounts the expulsion of children from the Kathmandu Valley by the then king Rana Bahadur Shah, who feared they would spread smallpox.  Written by an anonymous composer, the lament in Nepal Bhasa dates from the early 19th century.
The song describes how the king ordered the children and their parents to be rounded up and driven to eastern Nepal and across the Tama Koshi River (तामाकोशी). They suffered great hardships on the journey as they had no food, clothes or place to stay. The soldiers drove them forward by beating them with stinging nettles. Children died of cold and they were not allowed to be cremated or buried. So the parents had to throw the dead bodies into the Tama Koshi River.
The deportees were driven from Kathmandu to Bhaktapur, Banepa, Palanchok, Dolaghat, Dolakha and across the Tama Koshi. They were ordered to leave Nepal Mandala (Nepal Proper), whose eastern boundary is marked by the temple of Bhimsen in Dolakha. Many Newar settlements in the towns outside the Kathmandu Valley can be traced to this forced relocation.
The song's lilting tune and heart-rending words have made it an enduring classic. Sitalā Māju is one of the most well-known songs in Newar society. It is one of the six seasonal songs and is sung in the winter (December-January).
Children in the Kathmandu Valley were banished at the order of King Rana Bahadur Shah (reigned 1777-1805) to protect his infant son Girvan Yuddha Bikram Shah Deva (reigned 1799-1816) from catching smallpox. According to another version, the king was afraid that his wife would be infected, and so he had all the children in the valley sent away. Nevertheless, both Girvan Yuddha and the queen died of the disease.  Rana Bahadur was so enraged at the deities for not saving his wife despite his prayers that he had the image of Harati (alternative name: Ajima Dyah) (अजिमा द्य:) at Swayambhu desecrated.
The epic poem's title Sitalā Māju refers to the name of the goddess of smallpox according to Hindu and Buddhist traditions.

- Look at the plight of the people, Mother Sitala.
- It has never been heard of nor seen, but children cannot be kept in the country, The king has ordered it.
- With drummers beating drums and soldiers surrounding them, The children were expelled.
- Carrying pounded rice under their arms and their children on their backs, The people had to go across the Tama Koshi River.
- They went away carrying one child on their back, one on their hips, And dragging another one behind them.
- They departed from Kathmandu, spent the night at Bhaktapur, And visited the shrine of Mother Taleju.
- They departed from Bhaktapur, spent the night at Banepa, And visited the shrine of Chandeshwari.
- They departed from Banepa, spent the night at Palanchok, And visited the shrine of Bhagavati.
- They departed from Palanchok, spent the night at Dolaghat, And visited the shrine of Bhimsen.
- They departed from Dolaghat, spent the night at Tama Koshi, They had to go across the Tama Koshi River.
- They departed from Dolakha, reached the other side of the Tama Koshi River, And visited the shrine of Mahadev.
- There is no food to eat, there are no clothes to wear, And there is no place for me to stay.
- It was not a whip, it was not a cane, they were beaten with stinging nettles, By soldiers who surrounded them and drove them forward.
- We beg Mother Kachhala who gives smallpox blisters, Mother Sitala who fills them with water, Mother Bachhala who takes them away.
- If this child lives, we will release a pair of pigeons, We will offer jasmine flowers of gold and silver.
- At a place where no sunlight fell, the child died of cold, The mother and father beat their breasts and cried.
- It is not allowed to cremate the dead child or to bury him, What great suffering of the people.
- The father held half of the child's body, the mother held half of the child's body, And they threw it into the Tama Koshi River.
- The king had no compassion and ordered the children to be expelled, They had to go across the Tama Koshi River.
- King of Nepal, Rana Bahadur, The people suffered greatly.
- Don't, don't, Mother Sitala, I beg you a thousand times, Please deliver the people.
