It is hard to say which one was the "worst" as that is somewhat subjective.
The deadliest tornado season on record was that of 1925. On March 18 of that year the Tri-State tornado, the deadliest single tornado in U.S. history, killed 695 people. This death toll alone is greater than that of any other tornado season in the U.S. In all the 1925 tornado season killed 794 people.
The deadliest tornado season that does not owe its severity to a single tornado was the 2011 tornado season, which left 553 dead, with most deaths resulting from the Super Outbreak and the Joplin tornado. April 2011 had, by far, the highest number of tornadoes on record at 758. The month also produced the 2011 Super Outbreak of April 25-28. It was the largest tornado outbreak on record, spawning more than 350 tornadoes in just over 3 days including a 24-hour record of 207 tornadoes on April 27. Four of those tornadoes were rated EF5, marking only the second time that more than two F5 or EF5 tornadoes occurred in a single day. May 22 produced the Joplin, Missouri tornado, which killed 158 people and cost $2.8 billion in damage, the costliest single tornado in U.S. history and by far the deadliest in the era of modern forecasting.
The most severe tornado season on record was in 1974. That year produced a record 29 tornadoes rated F4 and 7 rated F5, most of them during the Super Outbreak of April 3-4, the most violent tornado outbreak on record. That outbreak produced 23 F4 tornadoes and 7 F5s in less than 24 hours. Despite the higher number of violent tornadoes, 1974 fell short of 2011 in deaths due to three extremely deadly tornadoes in 2011.
