Thomas Dixon (died July 25, 1886) was a Presbyterian architect born in Wilmington, Delaware and one of the founders of the Baltimore chapter of AIA. He was the father of minister Thomas Freeman Dixon, an 1893 graduate of Princeton Theological Seminary. He partnered with his brother, James M. Dixon, from 1851 until James's death in 1863. In 1871, he partnered with another well-known Baltimore architect Charles L. Carson for some time doing business from their offices at 117 Baltimore Street as Thomas Dixon and Charles L. Carson until sometime before 1877 when the partnership was dissolved. In 1827, he was elected Honorary Academician at the National Academy of Design.
He was married to Rebecca Howard, with whom he had one son: Rev. L. Freeman Dixon. He was living at 253 North Eutaw Street in Baltimore at the time of his death.
