Palestinian Christians (Arabic: مَسِيحِيُّون فِلَسْطِينِيُّون, romanized: Masīḥiyyūn Filasṭīniyyūn) are a religious community of the Palestinian people consisting of those who identify as Christians, including those who are cultural Christians in addition to those who actively adhere to Christianity. They are a religious minority within Palestine and Israel, as well as within the Palestinian diaspora. Applying the broader definition, which groups together individuals with full or partial Palestinian Christian ancestry, the term was applied to an estimated 500,000 people globally in the year 2000. As most Palestinians are Arabs, the overwhelming majority of Palestinian Christians also identify as Arab Christians.

Most Palestinian Christians belong to one of a number of Christian denominations, including Eastern Orthodoxy, Oriental Orthodoxy, Catholicism (both the Latin Church and the Eastern Catholic Churches), Anglicanism, and Protestantism (such as Lutheranism), among others. In the 1990s, an estimate by Professor Bernard Sabella of Bethlehem University postulated that approximately 6.5% of the global Palestinian population was Christian, and that 56% of this figure was living outside of Palestine and Israel.

As of 2015^[update], Palestinian Christians comprise between 1% and 2.5% of the population of the West Bank, and about 3,000 (0.13%) of the population of the Gaza Strip. According to official British Mandate statistics, Christians accounted for 9.5% of the total population (and 10.8% of Palestine's Arabs) in 1922 and 7.9% of the total population in 1946. Over the course of the 1947–1949 Palestine war between the Palestinian Arabs and the Palestinian Jews, a large number of these Christians—as part of the Arab community—fled or were expelled by Jewish militias from what would become recognized as Israeli territory following the 1949 Armistice Agreements. Since the 1967 Arab–Israeli War, which resulted in Israel's occupation of the Palestinian territories (the Jordanian-annexed West Bank and the Egyptian-occupied Gaza Strip), the Palestinian Christian population has increased as a whole, but has decreased as a percentage of the total Palestinian population.

Many individuals of the Palestinian diaspora who identify as Christians are descendants of the post-1948 Palestinian Christian refugees who fled from the Arab–Israeli conflict and settled in Christian-majority countries.

Palestinian Christians of different denominations are united by a common ethnic and Christian identity, as well as the experience of a connection to the birthplace of Christianity and a role in caring for its holy sites. Many Palestinian Christians are descended from early Christians, and they have sometimes called themselves "living stones". Although religion is perceived as a partly divisive factor, the common Palestinian and Arab identity of Palestinian Christians is also shared with Palestinian Muslims.

That Christian Arabs in Palestine see themselves as Arab reflects also the fact that, as of the beginning of the twentieth century, they shared many of the same customs as their Muslim neighbors. In some respects, this was a consequence of Christians adopting what were essentially Islamic practices, many of which were derived of sharî'ah. In others, it was more the case that the customs shared by both Muslims and Christians derived from neither faith, but rather were a result of a process of syncretization, whereby what had once been pagan practices were later redefined as Christian and subsequently adopted by Muslims. This was especially evident in the fact that Palestine's Muslims and Christians shared many of the same feast days, in honor of the same saints, even if they referred to them by different names. "Shrines dedicated to St. George, for instance, were transformed into shrines honoring Khidr-Ilyas, a conflation of the Prophet Elijah and the mythical sprite Khidr". Added to this, many Muslims viewed local Christian churches as saints' shrines. Thus, for instance, "Muslim women having difficulties conceiving, for instance, might travel to Bethlehem to pray for a child before the Virgin Mary". It was even not uncommon for a Muslim to have his child baptized in a Christian church, in the name of Khaḍr.

In 2009, there were an estimated 50,000 Christians in the Palestinian territories, mostly in the West Bank, with about 3,000 in the Gaza Strip. In 2022, about 1,100 Christians lived in the Gaza Strip – down from over 1300 in 2014. About 80% of the Christian Palestinians live in an urban environment. In the West Bank, they are concentrated mostly in Jerusalem and its vicinity: Bethlehem, Beit Jala, Beit Sahour, Ramallah, Bir Zayt, Jifna, Ein Arik, Taybeh.

Of the total Christian population of 185,000 in Israel, about 80% are designated as Arabs, many of whom self-identify as Palestinian.
