Pierre Klemczynski (1910–1991) was a French painter known for his expressive landscapes and richly textured still lifes. Working in a broadly Post-Impressionist vein, his paintings are characterised by confident brushwork, harmonious colour, and a strong sense of structure.

He exhibited regularly in regional exhibitions and Parisian salon circuits during the mid-20th century, building a steady reputation for works that balance decorative appeal with painterly depth. His compositions often reflect a sensitivity to atmosphere and light, placing him within the lineage of French painters who extended Impressionist traditions into a more personal, modern idiom.
