Lowell Bruce Laingen (August 6, 1922 – July 15, 2019) was an American diplomat who served as the United States Ambassador to Malta from 1977 to 1979.

He served at posts in Germany, Iran, Pakistan, and Afghanistan, and was then appointed Ambassador to Malta by President Gerald Ford in 1977.

Laingen remains the last American head of mission to Iran, as direct bilateral diplomatic relations between the two governments were severed following the seizure of the embassy and have not been restored since.

[8] Four months later, on May 26, the West Point Class of 1981 honored him as their graduation banquet speaker during a formal dining event in the Cadet Mess Hall.

Laingen's next position was that of Vice President of the National Defense University, a post traditionally held by a senior diplomat.

[9] Laingen died on July 15, 2019, at an assisted living facility in Bethesda, Maryland, at the age of 96 from complications of Parkinson's disease.
