Paulino Alcántara Riestrá (7 October 1896 – 13 February 1964) was a Filipino and Spanish professional footballer and manager who played as a forward.

[10] Alcántara then joined Barcelona's youth team and within the same week, he made his first-team debut at the age of 15 years, 4 months and 18 days on 25 February 1912 against Catalá SC (founded only weeks before FC Barcelona) in the Campionat de Catalunya (Catalan football championship) at the Camp de la Indústria, in front of about 100 fans.

He went on to help the club win two Campionat de Catalunya in 1913 and 1916 and the 1913 Copa del Rey (Spanish Cup), in which he missed the final that ended in a 2–2 draw with Real Sociedad, but then played in the replay as Barcelona came-out as 2-1 winners.

There Alcántara continued his studies in medicine and played football for the country's reigning champions Bohemian Sporting Club.

Meanwhile, Barcelona had failed to win a major trophy in his absence and the club pleaded in vain with his parents to allow him to return to Spain.

The paying members of Barca's club membership, "Els Socis," demanded that Alcántara be switched back to his normal position, which saw him return to the forward line.

[16] In 1920 the club won another Copa del Rey and the Campionat de Catalunya, with Alcántara scoring in the 2–0 win over Athletic Bilbao in the Cup final.

The squad included Emilio Sagi Liñán, who formed a partnership with Alcántara as well as Ricardo Zamora, Josep Samitier and Félix Sesúmaga.

This marked the beginning of the club's first golden era and saw them dominate both the Campionat de Catalunya and the Copa del Rey.

In May 1915, he was a member of the Catalan side that participated in the first edition of the Prince of Asturias Cup, an inter-regional competition organized by the RFEF.

[23] Alcántara retired on 3 July 1927 in order to become a doctor at age 31, the same day that FC Barcelona played against Spain in a testimonial match in his honour.

[24] In 1951, Alcántara was one of three selectors, along with Félix Quesada and Luís Iceta, that coached Spain for three games against Switzerland, Belgium and Sweden.

On 4 August 1936, he became a soldier and fled to Andorra and France after Franco's coup failed to take the city of Barcelona on 18 July 1936.

In 1936 Alcántara was a Carlist volunteer and participated in numerous military operations of the nationalist troops of Francisco Franco.

During the Spanish Civil War, Alcántara was Lieutenant of the first battalion of the Brigade Legionary Black Arrows[27] (Frecce Nere).

During the Spanish State and World War II period, Alcántara was a Chief of the Falange Española Tradicionalista y de las JONS.
