Mihály Iglói (September 5, 1908 – January 4, 1998) was a Hungarian distance running coach. Iglói coached runners such as Sándor Iharos, István Rózsavölgyi, László Tábori, Bob Schul and Jim Beatty. Counting both outdoors and indoors, and distances no longer officially recognized, Iglói's students achieved 49 world records.
Iglói was a notable runner in the 1930s. A multiple-time Hungarian champion, Iglói participated in the 1500 metres at the 1936 Summer Olympics in Berlin, but was eliminated in the heats. Iglói became the coach of Honvéd Budapest, then the Hungarian army club, in 1950, and the results of his pupils steadily improved.
The first world records for the Honvéd Budapest runners came as team efforts in the uncommon 4 × 1500 m relay in 1953 and 1954. Wholesale individual record breaking began on May 14, 1955, with Sándor Iharos beating Gaston Reiff's old 3000 metres record in Budapest with a time of 7:55.6. By the end of that year, Iharos held the world records over 1500 metres, 3000 metres, two miles and 5000 metres. István Rózsavölgyi had smashed the previous record over 2000 metres by almost five seconds with a time of 5:02.2; this was arguably the most impressive single mark by any of Iglói's Hungarian pupils, and lasted longer than any of Iharos' records. (It was eventually broken by Michel Jazy on June 14, 1962 with a time of 5:01.6.) László Tábori had tied Iharos' 1500m mark, and had become the third man in the world to run a four-minute mile.
