Shlosberg will be awarded the prize in Bonn, Germany on June 12, coinciding with the Russia Day national holiday, said chairman of the foundation's board of trustees Vladimir Kara-Murza Jr., The Moscow Times wrote.
A total of 45 people were nominated for the award before five finalists were selected by a poll on the website for the Novaya Gazeta newspaper. The overall winner was chosen by secret ballot.
The five finalists also included Moscow activist Ildar Dadin, writer Viktor Shenderovich, opposition politician Alexei Navalny and former Ukrainian military pilot Nadiya Savchenko, who has been sentenced to 22 years in prison by a Russian court, Novaya Gazeta reported.
"I am grateful to receive this award, but it's a sad award; it is not a reason for joy. It was created in the memory of the slain man who defended his beliefs. It would be much better if he was alive," Lev Shlosberg told the Moscow Times Monday.

The foundation provides assistance to "people persecuted in Russia for political reasons," and was created six months after Boris Nemtsov's murder on the Bolshoi Moskvoretsky Bridge near the Kremlin.
The prize for "courage in defending the values of freedom and democracy in Russia" will be awarded by the foundation once a year.
Lev Shlosberg is the publisher of an independent newspaper in the northwestern city of Pskov and a former member of Pskov's regional parliament for liberal opposition party Yabloko.

Russia's Chief Military Prosecutor refused to disclose information on the deaths, calling it a "state secret."
A week after Shlosberg's newspaper published the probe into the funerals of the two soldiers allegedly killed while fighting in Ukraine, he was beaten unconscious near his home.
