Christy O’Connor Jnr (born 19 August 1948) is an Irish golfer. He is known as “Junior” because he is the nephew of another leading Irish golfer Christy O’Connor.

O’Connor was born in Galway. He turned professional in 1967. The European Tour officially began in 1972, and O’Connor made the top hundred on the Order of Merit in each of its first twenty-one seasons, with a best ranking of seventh in 1975. He won four European Tour events. As a senior he has competed on both the European Seniors Tour and the U.S. based Champions Tour, and has won two Senior British Open titles (before it became one of the senior majors) and two Champions Tour events.

O’Connor played in the Ryder Cup twice. In 1975 he was a member of a losing Great Britain & Ireland team and in 1989 he was part of a European team which tied match the match to retain the trophy. His personal record was one win, three loses and no ties. His win over Fred Couples was best remembered for a stunning 2 iron shot on the last hole at the Belfry which he left just 4 feet from the hole.

O’Connor is also active in golf course design.
