The Leiden Children's Rights Observatory is an open access online database of case commentaries, written by international experts on children’s rights.

The commentaries refer to decisions of the UN Committee on the Rights of the Child (CRC) under the Optional Protocol to the Convention on the Rights of the Child on a Communication Procedure (OP3 or OPIC) related to children's rights.

The Leiden Children's Rights Observatory includes case commentaries written by international experts on children's rights, which offer original analyses of and critical reflections on the views of the CRC in the context of legal developments and emerging (global) trends related to children's rights. 

The Leiden Children's Rights Observatory is based at the Department of Child Law of Leiden Law School in the Netherlands.
