We present the coronagraph project for the 3.5m SPace Infrared telescope for Cosmology and Astrophysics (SPICA) space telescope which is schedule for launch around year 2015 by the Japanese HII-A rocket. This actively cooled (4.5 K), single aperture telescope will operate in the mid and far infrared spectral regions, and up to submillimetric wavelengths (200 microns). The lowest spectral region (5 to 20 microns), where the spatial resolution is the most favorable, will be dedicated to high contrast imaging with coronagraphy. In this contribution, we summarize the scientific goals, show our progresses in high-contrast imaging laboratory experiments, and study results from other expected coronagraph candidates such as the PIAA.
