The Holy Transfiguration of Our Lord Chapel is a historic Russian Orthodox church located near Ninilchik, Kenai Peninsula Borough, Alaska, that was built in 1901. It is an approximately 20-by-50-foot (6.1 m × 15.2 m) roughly cruxiform-shaped building, mainly designed by Alexi Andreev Oskolkoff who came from Sitka to supervise the building's construction. The 1901 church replaced an older church built near Ninilchik village's 1846 founding.
