English: Mueller Electric Company Building at 1587 East 31st Street in Cleveland, Ohio, in the United States. It was added to the National Register of Historic Places in 2016.

The two-story Commercial-style building was designed by The George S. Rider Co. The central section was originally erected in 1922, and consisted of steel post-and-beam and red brick building. It was 63 feet deep and 94 feet long (five bays wide). A 1925 addition added a second story to the one-story manufacturing space at the rear and to the south. A one-story addition was added to the north side of the building in 1936. A second story was added to the rear and a three-car garage against the south addition in 1946. A wrap-around one-story addition was added in 1956, and a story added to this in 1962. Another two-story addition was made to the north end in 1964, and second stories to the 1956 and 1962 southern portions in 1972. A final two-story addition was made to the north end in 1976. The interior space reflects an open industrial plan, with painted masonry walls and exposed structure.

Ralph S. Mueller invented the alligator clip, a spring-loaded metal clip with jaws resembling alligator's mouth and teeth. Today, the alligator clip is an indispensable and commonly used device in the testing and repair of electronics and charging of batteries and electronics.
