Ademir Ferreira dos Santos (born 1 June 1977), known as Ademir Fesan, is a Brazilian football coach.
Career Born in São Paulo, Fesan began his career as an assistant of Portuguesa Santista in 2008. After working as a youth coach at Grêmio Barueri, Brasil de Farroupilha, Juventus-SP and Santos, he was appointed head coach of Monte Azul in July 2013.
Fesan left AMA in August 2013, and spent more than a year without a club before joining Taboão da Serra as an under-20 coach in October 2014. He then moved to ABC as an assistant coach in March 2015, but also worked as an interim on two occasions.
Fesan was fired from ABC on 17 August 2015, and moved to Ceará in September, being the assistant of Lisca. He then worked with Marcelo Chamusca at Guarani, before rejoining Lisca's staff at Joinville and Internacional.
Fesan returned to CATS on 28 June 2017, now as a first team head coach. Sacked after just four matches on 24 July, he joined Atlético Tubarão as an under-20 coach in September.
Fesan reunited with Lisca at Paraná in 2017, and continued at the club in the following year, when he was appointed interim head coach on 16 February 2018, after Wagner Lopes was sacked. He was dismissed on 18 September of that year due to "financial difficulties".
Fesan rejoined Chamusca's staff at CRB, and followed him to Vitória and Cuiabá, all in the 2019 season. On 17 January 2020, he was appointed head coach of Grêmio Prudente.
On 19 January 2021, Fesan agreed to become Primavera's head coach. He led the club back to the Campeonato Paulista Série A2, but was sacked on 14 February 2022.
On 20 September 2022, Fesan was confirmed as FC Cascavel's head coach for the upcoming season, but was dismissed the following 5 February. He returned to Prudente eight days later, and reached the semi-finals of both the year's Campeonato Paulista Série A3 and the Copa Paulista, being knocked out by São José-SP on both competitions.
Fesan was sacked by Prudente on 4 February 2024, after just three matches into the season, and took over Comercial-SP eighteen days later. He left the latter after suffering relegation, and was named at the helm of São Bento on 19 April.
On 4 September 2024, Fesan left São Bento after being knocked out in the Copa Paulista, and was appointed Santa Catarina head coach on 18 October. He led the club to the semifinals of the 2025 Campeonato Catarinense, before departing on 11 March of that year.
On 19 March 2025, Inter de Limeira announced Fesan as their head coach. He led the club to a promotion from the Série D after winning 16 matches out of 30, but left on 7 October after failing to agree new terms.
On 15 October 2025, Fesan was confirmed as Água Santa's head coach for the ensuing campaign. The following 26 March, after a 3–0 loss to Ituano which diminished the club's promotion chances, he was sacked.
On 6 April 2026, Fesan signed a contract with Portuguesa, becoming their new head coach in the place of Fábio Matias. On 28 July, after being knocked out in the round of 16 of the Série D, he was dismissed.
