As a follow‐up to the first overview published in the International Zoo Yearbook in 1989, new data have been collected on the breeding of varanid lizards (Reptilia: Sauria: Varanidae) and these are presented in the form of a table. Taxonomic problems, husbandry techniques and some of the physiological aspects of reproduction are discussed. In general, it is concluded that our knowledge and understanding of varanid reproduction is increasing and the number of successful hatchings is growing accordingly. Further research is needed to enable us to learn more about the influence of certain factors, such as diet and light, on reproduction and to understand better the taxonomy of varanid lizards so that hybridization can be avoided.
