According to the figures released by the so-called Syrian Observatory for Human Rights on Thursday, violence claimed the lives of 76,021 in Syria in 2014.
The UK-based opposition group said nearly 18,000 civilians, including 3,501 children, were among those killed in Syria last year, describing 2014 as the deadliest year since the crisis broke out in the in the Arab state in March 2011.
Meanwhile, more than 32,700 militants from various rival extremist groups operating against the Syrian government also died on the battlefield in 2014, the report added.
According to the figures, the foreign-sponsored turmoil left over 22,600 Syrian army troops and pro-government forces dead in the Middle Eastern country.
The United Nations says more than 200,000 people have so far been killed and millions displaced due to the deadly crisis.
The Western powers and their regional allies - especially Qatar, Saudi Arabia and Turkey - are supporting the militants operating in Syria.
The government of Syrian President Bashar al-Assad has vowed to push ahead with its efforts to root out terrorism in the country and establish national reconciliation.
In the final hours of 2014 on Wednesday, Assad paid a visit to the army soldiers deployed to an area near the capital, Damascus, where he hailed the Syrian soldiers for their victories against terrorist groups operating in the country.
