Robert Clymer Hendrickson Sr. (August 12, 1898 – December 7, 1964) was an American attorney, Republican Party politician, and diplomat who represented New Jersey in the United States Senate from 1949 to 1955. He also served in local and county offices in Gloucester County, which he represented in the New Jersey Senate from 1934 to 1940, and served as New Jersey Treasurer from 1942 to 1949. After his term as United States Senator expired, President Dwight D. Eisenhower appointed him as United States Ambassador to New Zealand and Samoa from 1955 to 1956.
He was a key ally of Governor Alfred E. Driscoll, who managed Hendrickson's campaign for governor in 1940 and supported his campaign for the Senate in 1948. He won the nomination for Senate by gaining establishment support from local and county Republican leaders, which forced incumbent Albert W. Hawkes out of the race ahead of the primary. However, involvement in such intraparty fighting led to his withdrawal from the 1954 campaign, and he was succeeded by Clifford Case.
