Giuseppe Meazza (Italian pronunciation: [dʒuˈzɛppe meˈattsa]; 23 August 1910 – 21 August 1979) was an Italian football manager and player. Throughout his career, he played mainly for Inter Milan in the 1930s, scoring 284 goals in 408 games for the club, and winning three Serie A titles, as well as the Coppa Italia; he later also played for two seasons for local rivals Milan, as well as Turin rivals Juventus for one season, in addition to his spells with Varese and Atalanta. At the international level, he led Italy to win two consecutive World Cups: in 1934 on home soil, and in 1938 as captain, being named to the All-star Team. He is widely regarded as one of the best players of the 20th century, and one of the greatest Italian strikers in the history of the sport.

Along with Giovanni Ferrari, Guido Masetti and Eraldo Monzeglio, he is one of only four Italian players to have won two World Cups. Following his retirement, he served as a coach for the Italy national team, and with several Italian clubs, including his former club sides Inter and Atalanta, as well as Pro Patria, and Turkish club Beşiktaş; he was Italy's head coach at the 1952 Summer Olympics.

Due to his technical skill, prolific goalscoring, and creative ability, he was often given the nickname Il genio (The Genius) by the Italian press during his career. He has been ranked the fourth-best player in the history of the World Cup. A prolific forward, Meazza won the Serie A top-scorer award on three occasions in his career; with 216 goals in Serie A, he is the fourth all-time highest goal scorer in Serie A, alongside José Altafini, and with 33 goals, he is also the second highest goalscorer for the Italy national team. With 338 goals, he is the third-highest Italian goalscorer in all competitions. He is also the youngest player ever to score 100 goals in Serie A, a feat which he achieved at the age of 23 years and 32 days. San Siro, the principal stadium in his native city of Milan, which is today shared by two of his former clubs, Inter Milan and crosstown rivals A.C. Milan, was named Stadio Giuseppe Meazza in the player's honour on 3 March 1980. In 2011, he was posthumously inducted into the Italian Football Hall of Fame. Throughout his career, including friendlies, Meazza scored 552 goals.

Meazza was born in Porta Vittoria, Milan. Having lost his father in 1917 during the fighting of World War I at the age of seven, Peppe grew up in Milan with his mother, Ersilia who came from Mediglia, helping her sell fruit at the market. He began playing football at six years old, and started out playing barefoot with a ball made of rags on the streets for a team named the "Maestri Campionesi". At the age of twelve, his mother gave him permission to pursue a footballing career, and he began playing for Gloria F.C.. It was during this time that a fan gave Meazza his first pair of football boots.

At the age of 14, Meazza admired Milan, but was rejected by the team for his small physique. However, he was instead accepted by Milan's cross-city rivals Inter Milan.

Meazza's nickname, "il Balilla" ("The Little Boy"), was given to him in 1927 by his older teammate Leopoldo Conti, who thought "Peppìn", in Milanese dialect, who was only 17 when he joined the senior team, was too young to be associated to the senior team. He was surprised after Inter coach Árpád Weisz decided to give Meazza his debut for Inter in his place, commenting: "Now we even let the Balilla kids play!" The Opera Nazionale Balilla, the Fascist youth organisation which collected all children aged eight to 14 years, was established in 1926, hence why Conti felt it to be a suitable nickname for the young rookie. However, Meazza later scored two goals on his official debut, leaving Conti speechless.

Meazza scored two goals on his professional debut, which came in a 6–2 win against Milanese Unione Sportiva in the Coppa Volta di Como, on 12 September 1927. The following day, the Italian sports newspaper La Gazzetta dello Sport praised his game as "intelligent, fresh, quick". Meazza still holds the record for the most goals scored in a debut season in Serie A, with 31 goals in his first season (1929–30). The next season, he scored five goals in a single game, twice in one season: 6 January 1929 Inter against Pistoiese 9–1 and 17 March 1929 Inter v Verona 9–0. That same season (1928–29) on 12 May 1929, he scored six goals as Inter beat Venezia 10–2. 27 April 1930 was the first time Inter ever played Roma in Milan. Inter won 6–0 and Meazza scored four goals, scoring his first three within three minutes of the game.

With Meazza in the squad, Inter won three national championships in 1930, 1938 and 1940, and helped win the team's first Coppa Italia in 1939. In the 1930 deciding game, he scored a second half hat-trick to tie the game against Genoa after Inter had been down 3–0. He was top-scorer of Serie A three times (1930, 1936, 1938), top-scorer in the pre-Serie A year of 1929 and top scorer of the Central European Cup three times: 1930 (seven goals), 1933 (five goals) and 1936 (ten goals); he finished with a runners-up medal in the competition in 1933.
