Adenovirus
is a nuclear replicating DNA virus reliant on host RNA processing machinery. Processing and metabolism of cellular RNAs can be regulated by
METTL3
, which catalyzes the addition of N6-methyladenosine (m
6
A) to mRNAs. While m
6
A-modified adenoviral RNAs have been previously detected, the location and function of this mark within the infectious cycle is unknown. Since the complex adenovirus transcriptome includes overlapping spliced units that would impede accurate m

A mapping using short-read sequencing, here we profile m

A within the adenovirus transcriptome using a combination of meRIP-seq and direct RNA long-read sequencing to yield both nucleotide and transcript-resolved m

METTL3
specifically impacts viral late transcripts by reducing their splicing efficiency. These data showcase a new technique for m

A discovery within individual transcripts at nucleotide resolution, and highlight the role of m

A in regulating splicing of a viral pathogen.
