Tadeusz Brzeziński (February 21, 1896 – January 7, 1990) was a Polish consular official and the father of President Jimmy Carter's national security adviser, Zbigniew Brzezinski.

Brzeziński was born in the town of Złoczów, in what was then the Austro-Hungarian Empire (today Zolochiv, Lviv Oblast, Ukraine). He received his university education in Lwów (now the Ukrainian city Lviv), and in Vienna. As a volunteer in the Polish independence movement from 1918 to 1920, Brzeziński saw action in the Battle of Lwów during the Polish-Ukrainian War and against Soviet forces in the final Warsaw campaign of 1920. He entered the diplomatic-consular service of the new Polish Republic, serving in Essen, Germany; Lille, France; Leipzig, Germany; Kharkov, in the Soviet Ukraine, and Montreal, where he lived after the Communist takeover in Poland after World War II.

While in Leipzig, Germany, before World War II, Brzeziński became involved in efforts to rescue European Jews from Nazi concentration camps. In 1978, his efforts on behalf of the Jewish people were recognized by Israeli Prime Minister, Menachem Begin.

Brzeziński was consul general from 1938 until the Communist takeover of Poland at the end of World War II. He served as president of the Canadian Polish Congress from 1952 to 1962, and in 1975 helped create the World Polish Congress. Until his retirement, he worked for the Quebec province Ministry of Culture, setting up French-language centers in small towns.

Brzeziński died of pneumonia in Montreal at the age of 93. He was survived by his two sons: Zbigniew Brzezinski, President Jimmy Carter's national security advisor; and Lech Brzeziński, an engineer also living in Montreal.
