Alexandru "Alex" Papană (18 October 1906 – 17 April 1946) was a Romanian-American aviator and bobsledder who competed from the early 1930s to the late 1940s.

Competing for Romania in bobsleigh, he won two medals in the two-man event at the FIBT World Championships with a gold in 1933 and a bronze in 1934.

Papană also competed in two Winter Olympics, earning his best finish of fourth in the two-man event at Lake Placid, New York, in 1932.

At the 1936 Summer Olympics in Berlin, he competed in gliding (which was a demonstration sport), finishing a respectable 12th as the only representative from Romania.

In December of that year, Papană finished second with the Jungermeister in a race from Miami, Florida, to Havana, Cuba.
