Doyle & Patterson was an American architectural firm in Portland, Oregon from 1908 until 1914. It was a partnership of prolific architect Albert Ernest Doyle (1877–1928) and architect William B. Patterson.
The firm was founded upon receipt of a commission for the Meier and Frank Building in Portland. The firm lasted until 1914. Patterson served as the engineer and superintendent for the firm. With the addition of engineer James George Beach, son-in-law of prominent businessman Simon Benson, in 1911, the firm briefly became Doyle, Patterson & Beach, but Beach left in 1912, and the firm's name reverted to Doyle & Patterson. When less work was available in 1914, the partnership dissolved, and by 1915 Doyle was again working alone.
A number of works are listed on the National Register of Historic Places (NRHP).
