CHIJMES (pronounced "chimes") is a historic building complex in Singapore, which began life as a Catholic convent known as the Convent of the Holy Infant Jesus (CHIJ). The complex is located at Victoria Street in the Downtown Core, within the Central Area, Singapore's central business district.

The complex was used as a Catholic convent from 1852, with an acquired Caldwell House which was constructed in 1840–1841, an acquired Convent Orphanage house in 1855, the Convent of the Holy Infant Jesus Chapel in 1904 and an acquired hotel complex for the girls' school in 1933. The Caldwell House, currently a wedding venue, and the Gothic-style chapel, renamed as CHIJMES Hall, currently a function hall and also a wedding venue, have both been gazetted as national monuments. The complex was restored in 1996 for commercial purposes as a dining, shopping and entertainment centre with ethnic restaurants, shops and a function hall, providing a backdrop for musicals, recitals, theatrical performances and weddings.

After Father Jean-Marie Beurel consecrated the Cathedral of the Good Shepherd on 6 June 1847, he had an ambition to open a school for boys to be managed by the Brothers of the Christian Schools.

In 1848, Father Beurel asked the Straits Settlements government for land to build a school, but was refused. He left Singapore on 28 October 1850 for France. While he was in France, Father Beurel approached the Reverend Mother Saint François de Sales de Faudoas, the 14th Superior General of the Infant Jesus Sisters, to enlist some sisters in starting a school for girls. He returned to Singapore in 1852 with some Brothers from the Brothers of the Christian Schools and with them he later founded Saint Joseph's Institution at the former chapel in May 1852.

In July 1852, he asked the Straits Settlements Government once again for land next to the church for a charitable institution for girls, he was told that there was already sufficient land given to the church. Later in August 1852, Father Jean-Marie Beurel purchased the house at the corner of Victoria Street from H.C. Caldwell for the Sisters of the Holy Infant Jesus for 4,000 francs, the house was since known as the Caldwell House.

In October 1852, the four Sisters of the Holy Infant Jesus, Reverend Mother Mathilde Raclot, Mother Appollinaire, Mother Gaetan Gervais and Sister Gregory Connolly arrived in Penang after having travelled overland from their native country in caravans. Mother Mathilde Raclot, leader of this group, was to become a key personality in the early history of the Convent of the Holy Infant Jesus on Victoria Street.

On 2 February 1854, the Sisters sailed to Singapore from Penang on a mission to build a school for girls. On 5 February 1854, they reached the island's shores and took up residence at the Caldwell House.

The nuns began taking in pupils only ten days after moving in, establishing the first CHIJ school in Singapore. Reverend Mother Mathilde staffed her school with sisters from the parent Society, the Institute of the Charitable Schools of the Holy Infant Jesus of Saint Maur. She dedicated 20 years of her life turning the convent into a school, a house at the corner of the Stamford Road and North Bridge Road was acquired in 1855 to serve as an orphanage and refuge known as Home for Abandoned Babies for local girls and women and sometimes boys. Two classes were conducted, one for fee-paying students and another for orphans and the poor. Slowly, the nuns managed to restore the house into a simple but austere residence.
