Lena “Mac” McCarthy (b. Boston, 1992) is an American visual artist primarily painting and making large scale murals.

Her work explores states of mindfulness, healing and the divine feminine. Combining figurative symbols with abstracted forms, she creates metaphorical spaces that contemplate the spiritual and mysterious aspects of the world around us and our place within it.

In 2016, Lena began painting in the streets while living in Santiago, Chile and has since continued to paint in public spaces across the world. Her work ranges from ephemeral street paintings done in several hours to large scale mural works.

Her works are scattered across the globe on four continents; she has participated in numerous mural festivals in the US, Mexico and India and been an artist in residence with the Dripped on the Road traveling residency (2021, USA), La Sierra Foundation (2023, Colombia) and Watershed Studios (Ireland). In 2021 she constructed a large scale solo exhibition of her paintings and installation in Project B gallery (USA).

Lena lives and works in Massachusetts as well as around the world.
