The Carnegie Supernova Project (CSP) is a 5 year program whose goal is to obtain well-calibrated optical and Near-IR (NIR) light curves and spectrophotometry of 250 supernovae (SNe) of all types. In the NIR, type Ia SNe have a primary maximum in flux that typically occurs three days prior to B-band maximum; therefore, many of these SNe's NIR maxima are not caught by the observations. One way to indirectly determine the NIR maximum of a SN is to use light curve templates derived from more well-observed objects. Currently the best NIR SN light curve templates are produced using only a small number of SNe. We have constructed light curve templates using the SuperNova Object Oriented Python (SNOOPy) package based on 27 SNe in the YJH bands, which is more than double that of previous studies. Our 27 SNe all come from the CSP and all have excellent optical light curves and well defined NIR light curves. These new templates may be used to estimate the apparent magnitude at maximum and the SN decline rate, which can then be used to determine absolute magnitudes to help determine whether Type Ia SN are reliable standard candles in the NIR.
