Alberto y Los Trios Paraguayos was a trio from Paraguay formed by Luis Alberto del Paraná, with Digno García and Agustín Barboza. They toured the UK in the late 1950s and early 1960s, and released a number of UK records in the 1960s, on Philips Records in Europe and Epic Records in the United States. In expanded form beyond trio the group included performers of the accordion, orchestral harp, as well as guitars. The band leader, del Paraná, died in England in 1974.
The comedy rock band, Alberto y Lost Trios Paranoias, from the 1970s took their name from a satirical version of this band's name.
