The 32nd Edition Vuelta a España (Tour of Spain), a long-distance bicycle stage race and one of the three grand tours, was held from 26 April to 15 May 1977.

It consisted of 19 stages covering a total of 2,785 km (1,731 mi), and was won by Freddy Maertens of the Flandria cycling team.

While Maertens dominated the race he won the General Classification by less than 3:00.

The domination was from his record shattering 13 stages wins including the first and the last.

There was also an award for the best Spanish rider in the general classification, won by Miguel María Lasa, and a team classification won by Teka.
