Algimantas Mykolas Dailidė (12 March 1921 – 2015) was an official of the Nazi-sponsored Lithuanian Security Police during World War II. After the war, Dailidė sought refuge in the United States, saying he had been a "forester." While in the United States, Dailidė lived in both Florida and Cleveland, Ohio. He was a real estate agent until he retired to Gulfport, Florida. His citizenship was revoked in 1997 and he is variously reported as having left the United States on his own or having been deported in 2004.
Dailidė was born in Kaunas. In 2006, a Lithuanian court convicted him of having arrested twelve Jews who tried to flee from the Vilna Ghetto, and for arresting two Polish nationals who subsequently became political prisoners; however, he was not sentenced to prison "because he is very old and does not pose danger to society". In 2008, Haaretz reported that he lived in Kirchberg, Germany. However, Dailidė died in 2015 and was buried at Spring Grove Cemetery in Medina, Ohio, United States, yet he was included in the list of Nazi war criminals facing possible prosecution in 2019.
