We describe the design, fabrication, and characterization of an all-dielectric metamaterial operating in the thermal infrared.  The metamaterial is based on cubic dielectric resonators fabricated from Tellurium and arrayed on a Barium Fluoride substrate.  As predicted by simulation, the metamaterial exhibits a magnetic resonance near 10 um wavelength, and an electric resonance at a shorter wavelength.  The retrieved effective parameters reveal negative permeability (permittivity) in the vicinity of the magnetic (electric) resonance.  This work represents a first step toward the development of low loss infrared metamaterials suitable for device applications
