'''WISE 2056+1459'''，全称为'''WISEPC J205628.90+145953.3'''，是[[广域红外线巡天探测卫星]]（WISE）于2011年在[[海豚座]]发现的一颗Y0型[[棕矮星]]<ref name="Kirkpatrick2011v1"/>。它和[[WISE 0410+1502]]，[[WISE 1405+5534]]，[[WISE 1541-2250]]，[[WISE 1738+2732]]以及[[WISE 1828+2650]]一起被公布，这六颗恒星是人类发现的第一批的[[恒星分类|Y型]]棕矮星。

利用光度测量出WISE 1405+5534的距离为7.7[[秒差距]]（25.1[[光年]]）<ref name="Kirkpatrick2011v1"/>，而利用光谱分光测量的距离为3.0 +3.4/-0.6秒差距（9.8 +11.1/-2.0光年）<ref name="Cushing2011v1"/>。它的表面温度大约为350（300-400）[[热力学温标|K]]<ref name="Cushing2011v1"/>。
