Atlético Clube de Portugal is a Portuguese sports club based in the parish of Alcântara, in the west side of Lisbon.

Historically, it also had sections for field hockey, swimming, sport fishing, cycling, table tennis, rugby, volleyball, gymnastics, triathlon, and handball.

Atlético Clube de Portugal was formed when two clubs from west Lisbon, Carcavelinhos and União, merged to create a stronger team.

By combining the talent and resources of two of Lisbon's strongest teams, the club achieved outstanding results in football, basketball, and field hockey.

The rugby section, composed of former students from the Instituto Superior de Agronomia, won two Regional Championships of Lisbon.

In 1951, Atlético was awarded the rank of Official of the Military Order of Christ for its cultural and athletic contributions to national sports.

The football team began to feature players from the club's own schools, such as Orlando Paulos, Tomé Antunes, Vítor Lopes, Carlos Gomes, and Germano de Figueiredo.

The 1970s and 1980s were marked by achievements in amateur sports, particularly basketball, which produced several generations of talented athletes and won numerous titles.

The club lost management of the Alvito Municipal Pools, and the board resigned in April 2017, calling for early elections.

[17] Following the split from the SAD at the conclusion of the 2015–16 season under the Armando Hipólito administration, the club registered a team with the Lisbon Football Association.

Neighbors Santo António de Lisboa secured promotion in a championship won by Mem Martins.

[19] In the 2017–18 season, the club announced its entry into women's football, forming a team to compete in the Division of Promotion and the Cup of Portugal.

In the 2022–23 season, the club made history by earning promotion to Liga 3 for the first time and becoming champions of the Campeonato de Portugal.

During the 2023 season, a new SAD was formed and 90% of the team was purchased by Signature Football Holdings, an investment group led by former New York City council speaker Gifford Miller.

[22] In the early years of the club, matches were also played at the Campo de Santo Amaro, which had been the home of União Foot-Ball Lisboa.

The Engenheiro Santos e Castro Pavilion, located next to the Estádio da Tapadinha, was constructed in 1972 to cater for indoor sports.
