Irving Bedell Dudley (November 30, 1861 – November 27, 1911) was an American lawyer and diplomat, who served as United States Ambassador to Brazil from 1907 to 1911.
Ohio, the son of a minister and his wife, Dudley studied at  Kenyon College, graduating in 1882, before continuing to study law at Columbian University (now  George Washington University), graduating in 1885; he was admitted to the bar that year, and worked for the  War Department. 
Three years later, in 1888, he moved to
San Diego, California, where he was later elected a judge in 1890. 
Republican, Dudley was appointed  United States Minister to Peru by President William McKinley on June 25, 1897; he took up his post in September of that year.  
In December 1906,
McKinley's successor,  Theodore Roosevelt, appointed Dudley to be United States Ambassador to Brazil, a post he took up in April 1907.
Illness dogged Dudley and his wife during his career,
  and would ultimately contribute to his death: after staying at  Johns Hopkins Hospital for treatment of an unrelated complaint, he died there of heart failure three days before his birthday.   
His wife would die in 1960, at the age of 87.
