Sirak Melkonian (15 October 1930 – 17 August 2024; Persian: سیراک ملکنیان, Armenian: Սիրակ Մելքոնյան) was an Iranian-Armenian painter and one of the pioneers of modern art in Iran.

At the age of 12, with his father's support, Melkonian began learning oil painting under the tutelage of an Assyrian painter named Alex Gevargiz.

Alongside a group of artists centered around Marcos Grigorian, he played a key role in shifting figurative painting in Iran—originally influenced by Impressionism—towards Expressionism.

This group sought not only to transform the form and structure of painting but also to move beyond a romantic engagement with tradition and its mere depiction.

By using warm, harmonious colors, he revealed his keen attention to composition and the juxtaposition of geometric shapes derived from nature, along with the impactful element of line.

The nature represented in his works carries a more mystical and intuitive reflection of the earth, of its elements, and other transcendent concepts that guide the viewer towards an unknown and sacred realm.
