Paul Henry was an Irish artist best known for his landscape scenes of the West of Ireland in the Post-Impressionist style.

Henry, born in Belfast to Reverend Robert Mitchell Henry and Kate Ann Berry, commenced his artistic journey at Methodist College Belfast in 1882, where his regular drawing practice began. At fifteen, he transitioned to the Royal Belfast Academical Institution. After studying at the Belfast School of Art, he further honed his skills in Paris at the Académie Julian and Whistler's Académie Carmen in 1898.

In 1903, he married the painter Grace Henry, and by 1910, they returned to Ireland. Living on Achill Island until 1919, Henry mastered capturing the unique play of light and landscape in the West of Ireland. He relocated to Dublin in 1919, co-founding the Society of Dublin Painters in 1920. Henry, renowned for designing railway posters, faced personal changes, separating from his first wife in 1929 and marrying artist Mabel Young.

Throughout the 1920s and 1930s, Henry was Ireland's prominent artist, leaving a lasting impact on the perception of the west of Ireland. While he limited experimentation after leaving Achill, his work, influenced by his red-green color blindness, comprises a significant collection of impactful images. Sadly, he lost his sight in 1945 and did not regain it before his passing.

Henry's artistic legacy lives on through exhibitions, with a commemorative display at Trinity College, Dublin, in 1973 and a major exhibition at the National Gallery of Ireland in 2004.
