Marcos Pinheiro Pizzelli (pronounced , Armenian: Մարկոս Պինեյրո Պիզզելլի, born 3 October 1984), commonly known as Marcos, is a Brazilian-born Armenian footballer who is the captain for FC Aktobe and plays for the Armenia national team.
He started his career at the Brazilian club São Carlos as a youth from 2000 to 2005. In 2006, the young talent spotted by an agent from Ararat Yerevan, which soon recruited Pizzelli. His debut took place on 30 April in a game against Ulisses. Pizzelli entered the field in the 58th minute of the match, replacing Tigran Yesayan. His first goal for Ararat happened on 16 June in another game against Ulisses. For the first season Pizzelli focused on adaptation, and the next was on scoring goals. With its high performance, Pizzelli was the leading scorer in the Armenian Premier League twice with Ararat, scoring 22 goals during the 2007 Armenian Premier League and scoring 17 goals during that 2008 Armenian Premier League. As a result of the financial problems that have befallen Ararat, the club has decided to loan Pizzelli to the amateur club of the French 5th Division – Ararat (Issy-les-Moulineaux).
