Old North End Historic District, Historic residential district in Colorado Springs, United States.

The Old North End Historic District is a residential neighborhood north of Colorado College, bounded roughly by Monument Valley Park, an alley between Weber and Nevada Streets, and Uintah and Lilac Streets. Its houses, built between 1885 and 1965, include Spanish Colonial Revival, Georgian Revival, Mission, Modern Movement, International Style and Bungalow designs by architects such as Charles Thomas, Thomas MacLaren and E.C.G. Robinson.

The first building was the Columbian Club, a three-story Victorian house for female Colorado College students built around 1881 by president Edward Payson Tenney; it burned on January 1, 1884. By 1888 the area was mostly grassland with a few houses. Growth came between 1890 and 1910, driven by Cripple Creek and Victor gold mines and the more than 400 mining companies in the city. The district was listed on the National Register in 1982 and expanded and renamed in September 2015.

Wood Avenue's 1200 and 1300 blocks were nicknamed Millionaires Row for the mansions of some 50 North End millionaires, among them mine owners Nelson B. Williams and James Ferguson Burns, whose Williams Burns Mansion at 1315 Wood Avenue was later converted to apartments. The street was originally named Earl's Court. Several homes passed to Colorado College, including Stewart House and Charles L. Tutt Sr.'s house at Uintah and Cascade, now the Tutt Alumni House.

The district runs north of Colorado College, bounded by Monument Valley Park, the alley between Weber and Nevada Streets, and Uintah and Lilac Streets. The 1200 and 1300 blocks of Wood Avenue, once nicknamed Millionaires Row, hold the largest houses. A restored tuberculosis tent cottage stands at Jackson Street and Cascade Avenue.

A fully restored tuberculosis tent cottage with early 20th-century furnishings stands at Jackson Street and Cascade Avenue, a remnant of the era when patients came to Colorado Springs for its dry mountain air. Marshall Sprague was among those who moved to the neighborhood for a cure.
