Albert Ramos Viñolas (Spanish pronunciation: [alˈβeɾ ˈramos βiˈɲolas]; born 17 January 1988) is a former Spanish professional tennis player. He reached a career-high ATP singles ranking of world No. 17, in May 2017, after the final of the 2017 Monte Carlo Masters.

Ramos Viñolas has participated in the finals of six Futures tournaments, four of which he won. He lost in the finals of two ATP Challenger Tour tournaments (in Seville against his compatriot Pere Riba and in Palermo against Romanian player Adrian Ungur). In 2010 he won his first Challenger final in San Sebastián, defeating Benoît Paire.

As World No. 167, Albert Ramos Viñolas began 2010 nearly 300 positions higher than the start of the previous season. He lost in the qualifying rounds of Doha, Sydney and the Australian Open before returning to Challenger tournaments for the next three months. After qualifying into the main draw of the Barcelona Open, and securing a straight sets victory in the first round, Ramos Viñolas defeated World No. 12 Fernando González in three close sets. Despite losing to Ernests Gulbis in the third round, his upset over Gonzalez increased his confidence going forward.

Successive losses in the qualifying rounds of the French Open, and Wimbledon led to a dip in his rankings, however success at the San Sebastián, Seville and various other Challenger tournaments, gave Ramos Viñolas a ranking of World No. 123 to finish off his season.

Ramos Viñolas played a combination of ATP World Tour events, and Challenger tournaments over the course of 2011. Second round losses at the Chile and Argentina Open to Fabio Fognini, and Tommy Robredo respectively, gave Ramos Viñolas direct entrance into his first ATP tournaments. He tasted his first grand slam success at the French Open after a first round victory over Javier Martí. He lost to eventual quarterfinalist and World No. 5 Robin Söderling in the second round.

After victories in Milan and again at the San Sebastián Challenger, Ramos Viñolas made it to his first ATP Quarterfinal at the Romanian Open, losing to Florian Mayer in straight sets. His performance in Bucharest allowed Ramos Viñolas' ranking to peak below 100 at World No. 87. Following an impressive win over Marin Čilić in the first round of the Shanghai Masters, Ramos Viñolas finished his year at World No. 66.

At the 2012 Indian Wells Masters, he won over Richard Gasquet to reach the third round, where he fell to Pablo Andújar. At the 2012 Miami Masters, he defeated world no. 15 player Feliciano López, then lost to Gasquet in the third round. His lone ATP final came in the 2012 Grand Prix Hassan II in Casablanca, which he lost to reigning champion Andújar in an all-Spanish affair.

At the 2013 Miami Masters, Ramos Viñolas beat world no. 14 Juan Mónaco and former world no. 4 James Blake to reach the fourth round, where he lost to Jürgen Melzer. At the 2013 Barcelona Open, he defeated Jerzy Janowicz and world no. 15 Kei Nishikori, after which Rafael Nadal defeated him in the quarterfinals.
