The Kaehler–Rector House is a historic house located at 408 W. 25th St. in Merced, California. Built in the early 1890s, the house was designed by architect Louis Wegner in the Queen Anne style. The house's design includes a corner tower with a conical roof, a veranda extending to the front and east sides of the house, and a complex roof design that includes both gabled and hipped sections. A 1905 history of the San Joaquin Valley called the house "one of the finest in Merced County."
