%X We present the high-pressure synthesis of a novel doubly ordered perovskite NaYbZnWO<sub>6</sub> composed of the rare earth magnetic Yb<sup>3+</sup> ions and its comprehensive magnetic characterization. The structure consists of alternating layers of Yb<sup>3+</sup> and Na<sup>+</sup> ions along the c-axis, with Yb<sup>3+</sup> ions forming slightly distorted two-dimensional (2D) square lattices of kite-shape (Yb<sup>3+</sup>)4 units. Low-temperature magnetic susceptibility measurements indicate that the ground state of Yb<sup>3+</sup> can be described by an effective J<sub>eff</sub> = 1/2 Kramers doublet. Further, specific heat analysis reveals an internal magnetic field of the order of 1.48 K; however, magnetization data do not exhibit magnetic ordering down to 0.4 K. The spin exchanges of NaYbZnWO<sub>6</sub> evaluated by density functional theory (DFT) calculations unveil spin frustration in the compound. These findings suggest that NaYbZnWO<sub>6</sub> is a promising candidate for realizing a magnetically disordered quantum state.
