1987 Australian Open – Men's singles

Defending champion Stefan Edberg defeated Pat Cash in the final, 6–3, 6–4, 3–6, 5–7, 6–3 to win the men's singles tennis title at the 1987 Australian Open. It was his second major singles title.

There was no Australian Open in 1986, due to the administrative changes to make the tournament the opening major of the year (as it had been before 1977). The 1987 championship therefore followed the 1985 tournament, held over a year earlier.

This was the last edition of the tournament to be held on grass courts, as it would switch to hardcourts the following year.
