Ronald Alejandro Vargas Aranguren (Spanish pronunciation: [ˈronal(d) ˈβaɾɣas];[a] born 2 December 1986) is a Venezuelan former professional footballer who played as a forward.

In the 2010–11 season Ronald started with top performances, scoring, among other goals, four braces against Westerlo, Charleroi, Zulte-Waregem and Standard Liège.

Kanu fed the ball to Vargas down the left wing, and the Venezuelan looked smooth and he moved infield past his marker.

[3] The American team New York Red Bulls and Basel were interested in Ronald Vargas, if Anderlecht managed to get Thorgan Hazard.

[9] On 24 January 2016, thanks to a strike by Venezuelan midfielder, AEK won 1–0 against PAOK and remain at the second Super League position, behind the previous year's champions Olympiacos.

[11] On 13 February 2016, Vargas scoring after Diego Buonanotte's missed penalty kick, helping his club to escape with a 1–0 win against the undefeated champions Olympiacos.

It was the key player coming as a substitute in the derby whereas referee sent off visitors' Alberto Botia, Luka Milivojević (for the penalty incident) and home team's Rodrigo Galo Brito, while Felipe Pardo suffered a strain injury during first half.

[13] Greek Cup's final against Olympiakos was most likely the last appearance of Vargas in season, as the 29-year-old international has suffered a left adductor strain injury.

The current contract of 30-year-old international expires at the end of 2016–17 season, and his agent wanted to ask technical director of the club Daniel Majstorovic if they are interested in extending it before January 2017 or not.

[18] In September 2017, Vargas signed for Australian A-League club, Newcastle Jets on a one-year deal as their marquee player for the 2017–18 season.

[19] In a Round 3 clash with the Brisbane Roar, Vargas suffered a compound fracture of the leg, ruling him out for a large part of the season, a short time in to his A-League career.

Venezuela beat Colombia 1–0 at the 2015 Copa América, the biggest upset of the tournament so far and their first victory over their South American neighbours in the history of the competition.

Vargas had an excellent performance, almost gave the Venezuelans the lead in the 27th minute, forcing David Ospina to make a fine reflex save.
