Echinopsis klingleriana Cárdenas (1965) Acanthocalycium klinglerianum is a species of cactus endemic to Bolivia.

The five to six whitish to yellowish radial spines are subulate and have a length of 2 to 3 cm (0.79 to 1.18 in).

The funnel-shaped, white flowers open at night and appear on the side of the shoots.

[3] Acanthocalycium klinglerianum is distributed in the Bolivian department of Santa Cruz in the province of Chiquitos in the lowlands of 350 to 450 meters of Chaco vegetation.

The specific epithet klingleriana honors the Austrian Franciscan priest Elmar Klingler (1905–1995), who settled in the Bolivian jungle in the village of Santa Teresia in 1954
