Algimantas Mykolas Dailidė (12 March 1921 – 2015) was a Lithuanian Nazi collaborator who was an official of the Nazi-sponsored Lithuanian Security Police (Saugumas) 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.^[1][2] He was a real estate agent until he retired to Gulfport, Florida. His citizenship was revoked in 1997,^[3] and he fled to Germany in 2004.^[1]

Dailidė was born in Kaunas in 1921. He joined the Saugumas in 1941 until he fled Lithuania to Germany as a refugee in 1944. He then went to the United States in 1950 as a non-quota immigrant under a DPA visa.^[4] In 2006, a Lithuanian court convicted him of having arrested twelve Jews, including women and children, and two Poles who tried to flee from the Vilna Ghetto, and were subsequently executed.^[5] Dailidė received a 5-year prison sentence, but it was not enforced "because he is very old and does not pose danger to society".^[6][7] In 2008, Haaretz reported that he lived in Kirchberg, Germany.^[1] However, online databases verify that Dailidė died in 2015, and was buried at Spring Grove Cemetery in Medina, Ohio, United States,^[8][9] yet he was included in the list of Nazi war criminals facing possible prosecution in 2019.^[2]
