We present the local HII region metallicity near the site of the recentlydiscovered multiply lensed supernova (SN; "SN Refsdal") at redshift 1.49. "SNRefsdal" is located at the outer spiral arm ($\sim$7 kpc) of the lensed hostgalaxy, which we have previously reported to exhibit a steep negativegalactocentric metallicity gradient. Based on our updated near-infraredintegral field spectroscopic data, the gas-phase metallicity averaged in anintrinsic radius of $\sim$ 550 pc surrounding an HII region $\sim$ 200 pc awayfrom the SN site is 12 + log(O/H)$_{\rm PP04N2}$ $\le$ 8.67. The metallicityaveraged over nine HII regions at similar galactocentric distances ($\sim$5-7kpc) as "SN Refsdal" is constrained to be 12 + log(O/H)$_{\rm PP04N2}$ $\le$8.11. Given the fortuitous discovery of "SN Refsdal" in an advantageouslylensed face-on spiral, this is the first observational constraint on the localmetallicity environment of an SN site at redshift $z>1$.
