  "abstract": "Detecting a pulsar associated with a supernova remnant (SNR) and/or pulsar wind nebula (PWN) is crucial for unraveling its formation history and pulsar wind dynamics, yet the association with a radio pulsar is observed only in a small fraction of known SNRs and PWNe. In this paper, we report the discovery of a young pulsar J1631$-$4722, associated with the Galactic SNR G336.7$+$0.5 using Murriyang, CSIRO's Parkes radio telescope. It is also potentially associated with a PWN revealed by the Rapid ASKAP (Australian Square Kilometre Array Pathfinder) Continuum Survey (RACS). This 118 ms pulsar has a high dispersion measure of 873 $\\mathrm{pc\\,cm^{-3}}$ and a rotation measure of $-$1004 $\\mathrm{rad\\,m^{-2}}$. Because of such a high DM, at frequencies below 2 GHz, the pulse profile is significantly scattered, making it effectively undetectable in previous pulsar surveys at $\\sim$1.4 GHz. Follow-up observations yield a period derivative of $\\dot{P} = 3.6 \\times 10^{-15}$, implying a characteristic age, $\\tau_{c} = 33\\,$kyr, and spin-down luminosity, $\\dot{E} = 1.3\\times10^{36}\\,$erg$\\,s^{-1}$. PSR$\\,$J1631$-$4722, with its high spin-down luminosity and potential link to a PWN, stands out as a promising source of the high-energy $\\gamma$-ray emission observed in the region.",
