The Egyptian featured in Liverpool's 2-2 draw with Spanish side Sevilla on Tuesday evening, scoring the club's second which sent them into the break with a slender advantage.
The striker collected 51 per cent of the vote on UEFA’s website to claim the prize after his deflected goal capped an impressive display.
Salah saw off competition from some of the world's best players including La Liga's Lionel Messi and Cristiano Ronaldo, who came second and third respectively.
Paris St-Germain's Neymar and fellow Premier League rivals Harry Kane and Romelu Lukaku were also among the shortlist.
Salah may not have matched his opponents' performance level but he has an entire country supporting him in these online fan polls.
"This is a country that is obsessed with football," Egyptian football fan Omar Ashraf told the Liverpool Echo.
"It’s intrinsically linked to politics, culture, and feuds between different cities. Mohamed Salah is quite literally the most unifying Egyptian person in years.
"Mohamed never played for El-Ahly or El-Zamalek, who are the big two in Egypt, before he left for Europe, so there was no reason for either of the massive contingents to turn on him."
And his following have made sure this isn't the only accolade Salah has picked up recently.
The 25-year-old also claimed Liverpool's Player of the Month award for August, before topping a fans poll for Liverpool Goal of the Month after his breakaway effort against Arsenal.
This is despite Trent Alexander-Arnold scoring his first Liverpool goal with a stunning free-kick away at Hoffenheim.
Salah and his Liverpool team-mates face Burnley at Anfield this weekend.
