Betaherpesvirinae is a subfamily of Herpesviridae distinguished by reproducing less quickly than other subfamilies of Herpesviridae.

Betaherpesvirinae establish latency (site where virus lies dormant until reactivated) in leukocytes. This is different from Alphaherpesvirinae, which establish latency in neurons, and Gammaherpesvirinae, which establish latency in cells of the immune system, such as B-cells.

The Herpesviridae Study Group has proposed that the subfamily Betaherpesvirinae be divided into the following four genera
