Alexandros Nikolopoulos

Alexandros Nikolopoulos (1875 – ?) was a Greek weightlifter. He competed at the 1896 Summer Olympics in Athens.

In the one-handed event now known as the snatch, Nikolopoulos finished third out of the four lifters. He lifted 57.0 kilograms with one hand, matching the silver medallist Viggo Jensen, but could only manage 40.0 kilograms with the other, the same as fourth-place finisher Sotirios Versis.
