We present ground-based mid-infrared observations of Class 0 protostars inLDN 1448. Of the five known protostars in this cloud, we detected two, L1448N:Aand L1448C, at 12.5, 17.9, 20.8, and 24.5 microns, and a third, L1448 IRS 2, at24.5 microns. We present high-resolution images of the detected sources, andphotometry or upper limits for all five Class 0 sources in this cloud. Withthese data, we are able to augment existing spectral energy distributions(SEDs) for all five objects and place them on an evolutionary status diagram.Comment: Accepted by the Astronomical Journal; 26 pages, 9 figure
