Robert Jay Sigel (born November 13, 1943) is an American professional golfer.

Although he remained an amateur he did occasionally compete in professional events on the PGA Tour.

Sigel was considering a professional golf career while in college, but injured his arm in an accident.

Sigel developed his own successful insurance business in the Philadelphia area for over 30 years.

The proceeds from this tournament benefit prostate cancer research at the University of Pennsylvania.

He joined the Senior PGA Tour in 1994 and won Rookie of the Year honors, when he earned 14 top-10 finishes and secured his first victory at the GTE West Classic.

Since joining the Champions Tour in 1994, Sigel has been sponsored by Global Management Consulting and technology services company Accenture.
