Bengt Anders Valter (Bengtolle) Oldinger (November 3, 1911, in Åmål – March 31, 1988, in Stockholm) was a Swedish painter, teacher, and draftsman.

[1] After training as an elementary school teacher at the Folkskoleseminariet in Karlstad [sv] and as an opera singer, he studied painting with Otte Sköld in Stockholm in 1937, and with André Lhote in Paris in 1947 and 1951.

Primarily, Oldinger painted in oil and acrylic, and was a draftsman who captured people in motion with a few lines.

In reviews, his strong coloring,[3] safe brushwork,[4] and ability to compose images are emphasized.

After his first exhibition at Galleri Paul Ambroise in Paris in 1959, he changed his signature from Bengtolle to Oldinger.
