More than 100 chemical modifications of RNA, termed the epitranscriptome, have been described, most of which occur in prokaryotic and eukaryotic ribosomal, transfer, and noncoding RNA and eukaryotic messenger RNA. DNA and RNA viruses can modify their RNA either directly via genome‐encoded enzymes or by hijacking the host enzymatic machinery. Among the many RNA modifications described to date, four play particularly important roles in promoting viral infection by facilitating viral gene expression and replication and by enabling escape from the host innate immune response. Here, we discuss our current understanding of the mechanisms by which the RNA modifications such as N6‐methyladenosine (m6A), N6,2′‐O‐dimethyladenosine (m6Am), 5‐methylcytidine (m5C), N4‐acetylcytidine (ac4C), and 2′‐O‐methylation (Nm) promote viral replication and/or suppress recognition by innate sensors and downstream activation of the host antiviral response.
