James Gordon MacArthur (December 8, 1937 – October 28, 2010) was an American actor best known for the role of Danny "Danno" Williams, the reliable second-in-command of the fictional Hawaiian State Police squad in the long-running television series Hawaii Five-O.

Born in Los Angeles, California, MacArthur was the adopted son of playwright Charles MacArthur, and his wife, actress Helen Hayes. He grew up in Nyack, New York, along with the MacArthurs' biological daughter, Mary. He was educated at Allen-Stevenson School in New York, and later at the Solebury School in New Hope, Pennsylvania, where he starred in basketball, football and baseball.

In his final year at Solebury, MacArthur played guard on the football team; captained the basketball team; was president of his class, the student government, and the Drama Club; rewrote the school's constitution; edited the school paper, The Scribe; and played Scrooge in a local presentation of A Christmas Carol. He also started dating a fellow student, Joyce Bulifant; they were married in November 1958 and divorced nine years later.

MacArthur grew up around the greatest literary and theatrical talent of the time. Lillian Gish was his godmother, and his family's guests included Ben Hecht, Harpo Marx, Robert Benchley, Beatrice Lillie, John Barrymore, and John Steinbeck. His first radio role was on the Theatre Guild on the Air, in 1948. Theatre Guild on the Air was the premier radio program of its day, producing one-hour plays that were performed in front of a live audience of 800. Helen Hayes accepted a role in one of the plays, which also had a small part for a child. Her son was asked if he would like to do it, and agreed.
