Irma Herminia Ledezma Tambo (born 10 October 1959) is a Bolivian businesswoman, politician, and rancher who served as a member of the Chamber of Deputies from Beni, representing circumscription 61 from 2015 to 2020.

She entered politics as a member of the Social Democratic Movement, representing the party in the Chamber of Deputies and serving as head of its Guayaramerín branch until 2020 before retiring upon the completion of her parliamentary term.

[1] She dedicated much of her professional career to the fields of commerce and cattle ranching,[2] two industries that rapidly expanded in the lowland Amazonian departments in the final decades of the twentieth century, driven, among other factors, by an influx of migration to Cobija, Guayaramerín, and Riberalta, as well as cross-border trade with Brazil.

[3] In Beni, in particular, the peripheral presence of the national government promoted the formation of a strong regional economic elite based in the agriculture, ranching, and lumber industries, who often took on public functions in the State's absence, such as the construction of local infrastructure.

[4] Such was the case with Ledezma, who made her entry into politics as a member of the nascent Social Democratic Movement (MDS), composing part of the party's regional directorate.
