Cosmic Leaf is a floor lamp designed by Ross Lovegrove for Artemide in 2009. The floor lamp is made of chrome-plated steel and the lighting part of the lamp is made of transparent methacrylate with an odd texture that creates a unique light. The Cosmic Leaf appears as a digital leaf from another world, with a reptile-like surface that collects both shadow and light. The floor lamp has a height of 192 cm and is a striking detail in the room in which it is placed.

In 2010, Cosmic Leaf won the Good Design Award from The Chicago Athenaeum.
