The Lewis Miller Cottage is a historic house at Whitfield and Vincent Avenues, on the grounds of the Chautauqua Institute in Chautauqua, New York. Built in 1875, it was the residence of Lewis Miller, co-founder of the Chautauqua movement. It was designated a National Historic Landmark on December 21, 1965.

The Lewis Miller Cottage stands in the village of Chautauqua, at the northwest corner of Vincent and Whitfield Avenues. It is a two-story wood-frame structure, with a broad gabled roof showing Stick style woodwork and large supporting brackets. It has a symmetrical front facade, with sash windows flanking the center entrance on the ground floor, and paired sash windows on the second floor, flanking a center doorway that provides access to the second-story balcony. The first-floor porch and second-floor balcony both have gingerbread balustrades.

The Lewis Miller Cottage is considered one of the earliest prefabricated structures in the United States. Miller brought the cottage from Akron, Ohio, and erected it at Chautauqua in 1875, where he entertained US President Ulysses S. Grant that summer.

Mina Miller Edison, Miller's daughter, spent summers at the cottage with her husband, inventor Thomas Alva Edison. She renovated the cottage in 1922. Among the changes, several of the first floor's rooms were made into one large room. Landscape architect Ellen Biddle Shipman developed extensive gardens around the cottage.

In 2016 the Chautauqua Foundation acquired the cottage from Miller descendants Ted Arnn and Nancy Kim Arnn.
