A multiple thermocouple assembly with a reduced wire count is configured for use in an ablation catheter tip. In at least one embodiment, the assembly comprises a first metal material comprising a plurality of junctions； a plurality of conductors comprising a second metal material, each conductor connected to the first metal material at one of the plurality of junctions； and a common conductor that is physically paired with at least one of the plurality of conductors at a corresponding common conductor junction such that the common conductor forms a thermocouple pair with each of the plurality of conductors.
