Marie Novello, also known as Marie Novello Williams (born Maria Williams; 31 March 1884 – 21 June 1928) was a Welsh pianist. She was one of Theodor Leschetizky's last students and performed in public from childhood. Her early death cut short a promising career just as she began to record for one of the major English labels, having already amassed a considerable discography for one of its second-rank competitors.
