當地時間2026年2月4日，烏克蘭總統澤倫斯基在接受法國電視二台（France 2）獨家專訪時，首次公開自2022年2月俄烏衝突爆發以來，烏克蘭軍方的官方傷亡統計數據。此舉立即引發國際關注，因官方數字與西方智庫及開源情報項目的估計存在明顯差異，凸顯戰爭真實人力損失的不確定性。

在訪談中，澤倫斯基指出，根據官方統計，四年間在戰場上正式陣亡的烏克蘭士兵（包含職業軍人與動員兵）共計約5.5萬人。他同時承認，這個數字並未涵蓋全部傷亡，官方尚有「大量人員」被列為失蹤，但未提供具體數字。作為參考，澤倫斯基在 2025 年 2 月曾提到，當時烏克蘭約有4.6萬人陣亡，另有約38萬人受傷，可見戰爭造成的傷亡持續累積。

澤倫斯基所公布的數據與外部估計差距甚大。美國戰略與國際問題研究中心（CSIS）在 2026 年1月發布報告稱，截至2025年底，烏克蘭軍隊死亡人數可能在10萬至14萬之間，而包含受傷與失蹤人員的總傷亡則高達50萬至60萬。此外，開源項目UALosses通過公開記錄驗證的資料顯示，已確認超過9.2萬名烏克蘭士兵陣亡，另有約8.9萬人失蹤。這些數據差距凸顯不同統計方法、定義差異及戰爭信息不透明所帶來的挑戰。

此次澤倫斯基公開數據的時機也具有政治意義，正值俄烏代表在阿布達比進行第二輪和平談判之際，雙方剛剛達成314名戰俘的交換協議。在這種背景下，傷亡數字不僅影響國內士氣，也對國際支持與談判立場具有高度敏感性。

另一方面，俄方曾多次宣稱烏克蘭去年損失巨大，但分析人士普遍認為俄方發布的數據屬於資訊戰的一部分，與烏方及西方智庫的估計存在顯著差異。因此，雖然澤倫斯基的公開說明被視為烏方少有的透明行動，但各方對真實傷亡規模的爭議仍持續存在，這也是衝突中最具爭議和情感衝擊的問題之一。

On February 4, 2026, local time, Ukrainian President Volodymyr Zelenskyy gave an exclusive interview to France 2 in which he publicly disclosed Ukraine’s official military casualty figures for the first time since the outbreak of the Russia–Ukraine war in February 2022. The announcement immediately drew international attention, as the figures differed noticeably from estimates released by Western think tanks and open-source intelligence projects, highlighting the ongoing uncertainty surrounding the true human cost of the conflict.

In the interview, Zelenskyy stated that, according to official Ukrainian military statistics, approximately 55,000 Ukrainian soldiers have been formally confirmed killed in action over the past four years. This figure includes both professional servicemen and mobilized personnel. He acknowledged, however, that the death toll does not capture the full scale of losses, noting that a “large number” of service members are officially classified as missing, though he declined to provide a precise number. For context, Zelenskyy had previously said in February 2025 that Ukraine had suffered around 46,000 military deaths and roughly 380,000 wounded at that time, suggesting a steady and heavy toll as the war dragged on.

The president’s figures stand in sharp contrast to assessments from external institutions. In a report published in January 2026, the U.S.-based Center for Strategic and International Studies (CSIS) estimated that by the end of 2025, Ukrainian military fatalities could range between 100,000 and 140,000. When wounded and missing personnel are included, CSIS placed total Ukrainian casualties at approximately 500,000 to 600,000. Similarly, the open-source verification project UALosses, which compiles data from publicly available records and confirmations, has documented more than 92,000 confirmed Ukrainian military deaths, along with roughly 89,000 personnel listed as missing. These figures underscore the wide gap between official disclosures and independent estimates, a discrepancy often attributed to differing methodologies, definitions, and the fog of war.

The timing of Zelenskyy’s disclosure is also politically significant. It coincided with the second round of peace talks between Ukrainian and Russian representatives in Abu Dhabi, where both sides had just agreed to a prisoner exchange involving 314 detainees. Against this backdrop, casualty figures have taken on heightened diplomatic sensitivity, as they influence domestic morale, international support, and negotiating positions.

Russia, for its part, has repeatedly claimed that Ukrainian losses in the previous year were extraordinarily high. However, statements from the Russian Ministry of Defense are widely viewed by analysts as part of an ongoing information war and often diverge sharply from both Ukrainian official figures and Western intelligence assessments. As a result, while Zelenskyy’s remarks marked a rare moment of transparency from Kyiv, the true scale of losses on all sides remains one of the most contested and emotionally charged aspects of the conflict.
