Hayley Mulcahy (also known as HayleyMulch) (born 1 September, 1993, in Cork City) is an Irish comic book artist and illustrator.
In 2011, Mulch launched the webcomic, VERMILION, a pilot story for her project, Space Officer Triggs. The webcomic is since on permanent hiatus, with a total of 24 pages. However, it has not been ruled out to re-work the story for a future plot in Triggs.
In 2015, Mulch illustrated the four page short science fiction story, The Invisible Heart, written by Seán Creagh, which was featured in the Cork Sci-Fi Comic. Later that year she released her first full-length comic, Das My Bai, as a digital release, before a physical printed version debuted at Kerry Comic Con in 2017. Das My Bai (colloquial dialect of saying "That's My Boy") is an all-ages comic about the life and times of her old Yorkshire Terrier, Jack.
Mulch has also contributed to the Irish webcomic, Tiny Wooden Pieces (created by Colin O'Mahony & Aileen Cudmore), drawing two guest comics along with writer Dave McNally.Mulch's next webcomic, Paradiso, is currently in production.
