The ILO Convention Concerning Minimum Age for Admission to Employment C138,^[1] is a convention adopted in 1973 by the International Labour Organization. It requires ratifying states to pursue a national policy designed to ensure the effective abolition of child labour and to raise progressively the minimum age for admission to employment or work. It is one of eight ILO fundamental conventions. Convention C138 replaces several similar ILO conventions in specific fields of labour.

Countries are free to specify a minimum age for labour, with a minimum of 15 years. A declaration of 14 years is also possible when for a specified period of time. Laws may also permit light work for children aged 13–15 (not harming their health or school work). The minimum age of 18 years is specified for work which "is likely to jeopardise the health, safety or morals of young persons". Definitions of the type of work and derogations are only possible after tripartite consultations (if such a system exists in the ratifying country).

The convention is a revision of several conventions for workers in specific areas. Upon entry into force, some of these conventions were closed for ratification and becoming a party to this convention automatically resulted in denunciation of the older ones. An overview of older minimum age conventions of ILO is shown below:

ILO Convention C138 entered into force one year after deposition of the first two ratifications (Cuba and Libya). As of July 2023 176 countries have ratified Convention C138. Initially, however, the pace of ratification of this convention was extremely slow. Therefore, an alternative Convention with a more limited scope was initiated in 1999.^[22] It concerns ILO Convention 182 concerning the Prohibition and Immediate Action for the Elimination of the Worst Forms of Child Labour.

Convention C138 enters into force for a ratifying country one year after ratification. This can be denounced^{[clarification needed]} every 10 years in the year after 10 years have passed (e.g. 19 June 2027 – 19 June 2028).
