Maurice Blieck, also known as Maurits Blieck, was a Belgian painter and etcher.

He studied at the Academy of Fine Arts in Brussels around 1894-1896. After his studies in Brussels, he perfected himself for some time in Paris.

He was a founding member of the Brussels artist association Le Sillon in 1893, along with Jef Lambeaux, Alfred Bastien, Jean Laudy and Maurice Wagemans, among others.

During World War I, he stayed successively in Paris and London. During this stay in London, he developed his own color palette with delicate lighting effects and colorful, atmospheric dreamscapes.

He would make his mark as a painter of portraits, figures, landscapes, cityscapes, marines and harbor views. His style moved toward realistic luminism with some impressionistic touches. He evolved toward symbolism along with Jules Merckaert and Paul Mathieu.

He painted portraits of his wife, the painter Frans Smeers and the man of letters Georges Eekhoud, among others. For his landscapes, he worked frequently in the vicinity of the Rook monastery outside Brussels and in the vicinity of Genk in the Limburg Kempen region. For his harbor scenes with figures of dock workers, he went to Antwerp.
