Francisco 'Paco' Bienzobas Ocáriz (born 26 March 1909 – died 30 April 1981) was a Spanish footballer who played as a forward.

Having spent most of his 16-year career with Real Sociedad - 196 official games and 109 goals- he was the first player to win the Pichichi Trophy award, given to the top scorer in La Liga.

Born in San Sebastián, Gipuzkoa, Bienzobas arrived at local Real Sociedad at the age of 17, from amateurs Unión Deportiva de San Sebastián, helping the Basque win the Regional Championship in his first year. He reached his first Copa del Rey final with the club in 1928, facing FC Barcelona in three matches (two 1–1 draws and a 1–3 loss).

In 1929, a national league was created, and Real Sociedad participated in La Liga's first edition, finishing fourth out of the ten clubs competing. Bienzobas scored 14 goals during the season, being the first player to be crowned Pichichi; he spent a further four years with the club, netting 39 goals in 65 league games.

In 1934, Bienzobas joined CA Osasuna, at the time in the Segunda División, helping the Navarrese immediately achieve promotion, but being immediately relegated back. The Spanish Civil War put a stop to his career for several years and, subsequently, he returned to Real Sociedad, retiring from football at the end of 1941–42 (aged 33) after playing in only five matches during the season, and amassing Spanish top division totals of 92 games and 50 goals.
