  "abstract": "We present the first search for the doubly Cabibbo-suppressed decays $D^0\\to K^+π^-η^\\prime$ and $D^+\\to K^+π^0η^\\prime$ using an $e^+e^-$ collision data sample corresponding to an integrated luminosity of 20.3 fb$^{-1}$, collected at a center-of-mass energy of 3.773 GeV with the Beijing Spectrometer III (BESIII) detector at the Beijing Electron-Positron Collider II (BEPCII). No significant signals are observed, and the upper limits on their decay branching fractions are set to be $3.0\\times 10^{-5}$ and $2.1\\times 10^{-5}$ at the 90% confidence level, respectively. By combining these results with the world-average branching fractions of the corresponding Cabibbo-favored decays, upper limits at the 90% confidence level are obtained on the ratios of doubly Cabibbo-suppressed to Cabibbo-favored branching fractions. The limits are determined to be $1.6\\times \\tan^4θ_C$ and $3.7\\times \\tan^4θ_C$ for $D^0\\to K^+π^-η^\\prime$ and $D^+\\to K^+π^0η^\\prime$, respectively, where $θ_C$ denotes the Cabibbo mixing angle.",
