Byron Vreeland (1844–1889) was an American architect practicing in Bozeman and Miles City, Montana, where he pioneered the profession.
Vreeland's early life and education are unknown, though he was trained as an architect.
In the late 1870s he and his brother, builder Frank W. Vreeland, arrived in Bozeman.
By 1882 Frank W. Vreeland had retired from the firm, and was replaced by Herman Kemna.
Simultaneously with this event, Vreeland relocated to Miles City, then a boomtown.
