Discrimination against transgender and intersex people is illegal in Portugal. In March 2011, President
Aníbal Cavaco Silva ratified the new
Law of Gender Identity (), which allows transgender persons to change their legal gender on birth certificates and other identity documents. On 24 May 2016, the Left Bloc introduced a bill to allow legal gender change solely based on self-determination. Similar bills were introduced by the
People–Animals–Nature party and the
Costa Government in November 2016 and May 2017, respectively. They were merged into one measure by a parliamentary committee and subsequently approved by the Parliament on 13 April 2018. On 9 May, President
Marcelo Rebelo de Sousa vetoed the bill. On 12 July, the Parliament adopted the bill with changes with regards to sex changes by minors aged 16 and 17, suggested by the President in his veto message. This time around, the President signed the bill on 31 July. It was published in the official journal on 7 August 2018 and took effect the following day. The law (Act No. 38/2018) allows an adult person to change their legal gender without any requirements. Minors aged 16 and 17 are able to do so with parental consent and a psychological opinion, confirming that their decision has been taken freely and without any outside pressure. The law also prohibits both direct and indirect discrimination based on gender identity, gender expression and sex characteristics, and bans non-consensual sex assignment treatment and
surgical intervention on intersex children. By October 2018, a total of 274 people, including 21 minors, had used the new gender recognition law to change their legal gender. The law has been cited by the
UN Human Rights Council as a model piece of legislation. In July 2019, the Minister of Science, Technology and Higher Education,
Manuel Heitor, issued recommendations for universities to amend the certificates of transgender people to properly reflect their gender identity. Similarly, that same month, Education Minister
Tiago Brandão Rodrigues published regulations for primary and secondary schools to facilitate transgender and intersex students. This includes using the student's preferred name, raising awareness, and training staff to handle discrimination cases and bullying. On March 20, 2026, the
Portuguese Assembly approved the first preliminary reading of three draft anti-trans bills by a vote of 151-79, with the right wing parties
PSD,
Chega, and
CDS-PP voting in favor and all other parties in the assembly (
PS,
Liberal Initiative,
LIVRE,
PCP, the
Left Bloc,
PAN, and
JPP) voting against it. The bills, which were introduced by the PSD, Chega, and CDS-PP parties, seek to repeal Act No. 38/2018, remove self-identification for trans people, force trans people to get medical diagnoses for name and gender changes, ban gender-affirming care for minors, re-legalize non-consensual surgery on intersex children, ban trans and nonbinary minors from changing their name or gender marker on official documents and ban the inclusion of “
gender ideology” in school curricula. The bills received widespread criticism from legal experts, medical professionals, and advocacy groups and were compared to recent bills restricting LGBTQ+ rights in
Russia and
Hungary. Legal experts expressed concerns that the bills were not only unconstitutional, but may also violate
European Union and
United Nations policies. Meanwhile,
Outright International and other international organizations united with over 70 Portuguese organizations to oppose the bills and hundreds of people protested outside the Assembly during the preliminary vote on March 20. Additionally, national medical organizations including the Portuguese Society of Clinical Sexology, the National Association of Medical Students, the Portuguese Medical Association and the Portuguese Order of Psychologists released statements opposing the bills, in addition to over 50 health professionals and academics who criticized the poor scientific rigor used to support the proposals. Following the preliminary vote on March 20, the
Left Bloc formally petitioned
Volker Türk, the United Nation's top human rights official, to weigh in on whether the bills would breach Portugal's treaty commitments. The bills will now go to specialized parliamentary committees for expert testimony and potential amendments before returning to the full Assembly for a final vote. If passed again, the bills will then be sent to the
president for approval. ==Military service==
