Arthur Oakley Coltman (A.O. Coltman) (1894, Edmonton, Middlesex – 1961, Cuckfield, Sussex) was an English architect practising in Malaya for 32 years where he worked as manager of the architecture firm Booty Edwards & Partners. He arrived in Malaya in 1925 and retired in 1957.

He was on active service during the First World War before working in the Transvaal, and was officially listed as an absentee member of the Transvaal Provincial Institute of Architects from about 1931 to 1938.

He was responsible for many of Kuala Lumpur's greatest Art Deco structures, including the Clock Tower, OCBC Building, and Oriental Building. He also designed the Anglo-Oriental Building near Merdeka Square, which is now known as Wisma Ekran; the Lee Rubber Building, on Jalan Tun H. S. Lee; the Rubber Research Institute, on Jalan Ampang; and the Odeon Cinema, on Jalan Tuanku Abdul Rahman.

Coltman died in Sussex, England at the age of 67 in 1961.

He worked on the buildings including:

1. Oriental Building Situated at Jalan Tun Perak (the former Java Street), next to the  SP7  KJ13  Masjid Jamek LRT station, the five-storey Oriental Building rose to the towering height of 82 feet and was the tallest in Kuala Lumpur.Originally called the Oriental Building.

2.The Lee Rubber Building or Nan Yi Building (Chinese: 南益大厦) sits on a prominent corner in Kuala Lumpur's Chinatown. This four-storey Art Deco building was commissioned in the early 1930s by the Lee Rubber Company, a multimillion-dollar enterprise set up by Lee Kong Chian (1893–1967), a Chinese businessman from the southern Malaysian state of Johor who was known as the 'rubber and pineapple king'.

3. Odeon Cinema: The thematic link between the Art Deco style and the new entertainment industry was also evident in the design of the Odeon Cinema (Chinese: 奥迪安戏院) on the corner of Jalan Tuanku Abdul Rahman and Jalan Dang Wangi (the former Batu Road and Campbell Road) in Kuala Lumpur. The Odeon Cinema was constructed in 1936 by the Cathay Organization. The standalone Odeon Cinema is one of the last few surviving colonial buildings in Kuala Lumpur. It has undergone various changes. It was acquired by Antenna Entertainments and operated as a cinema again between May 2011 and March 2015.

4. Clock Tower: Located at the Old Market Square (Medan Pasar Besar) near LRT Masjid Jamek in Kuala Lumpur's commercial centre, the Clock Tower is a distinctive architectural landmark. The tower was built to commemorate the coronation of England's King George VI in 1937. The memorial plaques were removed following independence. The sunburst motif is common in Art Deco design and is a prominent feature on the Clock Tower.

5. OCBC building: This building was designed by Coltman and built in 1937 to house the headquarters of the Oversea-Chinese Banking Corporation Limited in Malaysia, and is a masterpiece of the Art Deco style. Located at the junction of Jalan Hang Kasturi and Leboh Pasar Besar (just behind the Central Market), it has the advantage of double frontage.
