Sylviornithidae is an extinct family of flightless birds. Traditionally assumed to be within Galliformes, recent phylogenetic studies showcase that they rest outside of the galliform crown-group, making them the most recently lived non-galliform Pangalliformes. For many years it was considered a monotypic family consisting of Sylviornis alone, but recent studies show that Megavitiornis was part of this clade as well.
