The signatories of the Act of Independence of Lithuania were the twenty Lithuanian men who signed the Act of Independence of Lithuania on February 16, 1918. The signatories were elected to the Council of Lithuania by the Vilnius Conference in September 1917 and entrusted with the mission of establishing an independent Lithuanian state. The proclaimed independence was established only in late 1918, after Germany lost World War I and its troops retreated from Lithuanian territory. What followed was a long process of building the state, determining its borders, and gaining international diplomatic recognition. The signatories succeeded in their mission and independent Lithuania survived until the Soviet Union occupied the state on June 15, 1940.

Their political, professional, and social backgrounds were diverse. Several rose to political prominence; Antanas Smetona and Aleksandras Stulginskis were later elected Presidents of Lithuania and Jonas Vileišis went on to become mayor of Kaunas, the temporary capital of Lithuania. After Lithuania lost its independence during World War II, six of the surviving signatories were sent to prison or executed by the Soviet government and six others emigrated to Western countries.

The signatories came from a variety of social backgrounds. Four had been born to Lithuanian noble families: Donatas Malinauskas, Stanisław Narutowicz, Jonas Smilgevičius, and Mykolas Biržiška. The other 16 were the children of farmers. The eldest of the signatories was Jonas Basanavičius, who was 67 at the time, and the youngest Kazimieras Bizauskas, who was 25. Of the remainder, three were in their fifties, six were in their forties, eight were in their thirties, and one was in his twenties. All, with the exception of Saliamonas Banaitis, had completed tertiary education. In 1926 he enrolled at Kaunas University, but his studies were left unfinished due to his death in 1933. In terms of educational background, the council was dominated by eight lawyers. The group also included four priests, two agronomists, two financiers, one physician, one economist, and an engineer. The majority of the signatories had received their higher education outside of Lithuania, since at the time Lithuania had no universities - Vilnius University was closed after the January Uprising in 1863. Five graduated from Saint Petersburg University, four from Moscow University, and two from Saint Petersburg State Institute of Technology.

By faith, nineteen of the signatories were Roman Catholics, although Jonas Basanavičius was not practicing. Jokūbas Šernas was the only professed Protestant Reformer. At the time of the Act of Independence, six of the signatories were officially nonpartisan, seven were members of the conservative Lithuanian Christian Democratic Party, two were affiliated with the Lithuanian Nationalist Union and the Social Democratic Party, and Jonas Vileišis was affiliated with the Party of National Progress and the left-wing Lithuanian Popular Socialist Democratic Party.

The signatories had all been active in Lithuania's independence movement. Antanas Smetona, Donatas Malinauskas, and several others had participated in secret Lithuanian fellowships in the late 19th and early 20th centuries. These groups were involved in promoting the illegal distribution of Lithuanian-language publications using the Latin alphabet, which was banned by the Tsarist government from 1866 to 1904, as well as fighting other attempts at Russification by the authorities. Antanas Smetona, Steponas Kairys, Alfonsas Petrulis, and Mykolas Biržiška were expelled from their secondary schools for these activities. Jonas Basanavičius, the future chairman of the Council of Lithuania when the Act was signed, worked as a physician in Bulgaria and furthered the cause of public health there. Despite the demands of his medical work abroad, he contributed continuously to Lithuanian affairs. He organized the publication of a major underground newspaper, Aušra; its first issue appeared in 1883. Basanavičius was active in Bulgaria's political life as well, representing its Democratic party. Many of the signatories had participated in the 1905 Great Seimas of Vilnius, which shaped the political future of the Lithuanian state.

Most of the signatories remained active in the cultural and political life of independent Lithuania. Jonas Vileišis served in the Lithuanian Parliament and as mayor of Kaunas; Saliamonas Banaitis was involved in finance, opening several banks. Among the signatories were two future Presidents of Lithuania, Antanas Smetona and Aleksandras Stulginskis. Jonas Basanavičius returned to an academic life, pursuing his researches in Lithuanian culture and folklore. Five signatories died before World War II began; three died during the Nazi occupation of Lithuania. Those who did not emigrate to Western countries were arrested as political prisoners after Lithuania was occupied by the Soviet Union during World War II.

Aleksandras Stulginskis and Petras Klimas were sent to prison in Siberia by Soviet authorities, but survived and returned to Lithuania. Pranas Dovydaitis and Vladas Mironas were also sent to Siberia but died there. Kazys Bizauskas was shot along with a number of other prisoners on June 26, 1941, while being transported to a Soviet prison in Minsk. Donatas Malinauskas, along with many other civilians, was deported to Siberia and died there on November 30, 1942. His body was returned from Siberia in 1993 and reburied in Lithuania. Six of the surviving signatories emigrated to Western countries. Brothers Jurgis Šaulys and Kazimieras Steponas Šaulys died in Switzerland; Jonas Vailokaitis died in Germany; Antanas Smetona, Mykolas Biržiška and Steponas Kairys died in the United States.
