UPt3 is an unconventional heavy fermion superconductor with multiple low temperature superconducting transitions (550 mK and 500mK) and an enhanced Sommerfeld coefficient of around 430 mJ/mol-K^2 [1]. More recent theoretical work suggests that there may also be a topological aspect to the superconductivity [2]. Given the large Sommerfeld coefficient and the possibility of hybridization between the U 5<i>f</i> electrons and the conduction electrons in the system, UPt<sub>3</sub> shows signatures of being a good thermoelectric material. In this work, powder X-Ray diffraction, Energy-dispersive X-Ray spectroscopy, magnetic properties, resistivity, heat capacity, and thermoelectric measurements are carried out on an arc melted sample of UPt<sub>3</sub>. These results will be discussed.<br/><br/>[1] Sulpice, A., et al. J Low Temp Phys 62, 39–54 (1986)<br/>[2] Yasumasa Tsutsumi, et. al. J Phys. Soc. Japan, 82, 113707 (2013)
