Tallinn Children’s Home is a social welfare institution of the city of Tallinn, whose primary goal is to serve as a substitute home for orphans and other children who lack parental care.

Tallinn Children’s Home launched activity on 1 January 2001. The institution was created though a merger of various children’s homes located in Tallinn. The Tallinn Children's Home is Estonia’s largest children’s home, offering services to 500 children over the course of the year.

The structure consists of 12 different units. Six of them offer long-term substitute care for children left without parental care (Centre for Infants and Disabled Children, Kopli Centre, Lasnamäe Centre, Maarjamäe Centre, Mustamäe Centre and Nõmme Centre). Two units, the Children’s Shelter and the Young Children’s Shelter, offer around-the-clock assistance and support for children on a temporary basis. One unit, the Shelter for Mothers and Children, provides around-the-clock assistance on a temporary basis to mothers and children who are at risk. The Youth Home offers a youth home service for residents of the children’s home who have become adults. The Lasnamäe Centre offers occupational therapy for disabled children.

In the last ten years, Tallinn has renovated all of its children’s home buildings. The Tallinn Children’s Home centres have made a transition to a family system, meaning that children live as families in apartments with at least 5 rooms, a family has 6-10 children; 4 employees are attached to each family. In Maarjamäe the families live in separate buildings.

The Children's Home centres are currently located in large buildings, with 5-10 families in each. In the future, the children’s home centres will be reorganized into smaller duplexes or twin apartments in different districts of the city with occupancy of 16.
