JST Connectors refers to a family of electrical connectors made by the Japanese company JST.

JST Connectors in their most-recognizable form are white plastic connector housings and headers on PCBs.

JST Connectors are usually described using the series, pin-to-pin pitch, wire count and gender. For example, a 3 pin female JST XH connector would be described as:

JST XH 2.5mm 3-pin female

Wire-to-board connectors:

JST series	Pin-to-pin pitch	Pin rows	Current (Amp)	Voltage (Volt)	Wire size (AWG)	Shroud	Lock	Notes	Datasheet
VH	3.96 mm (0.156 in)	1	10	250	22 to 16	Yes/No	Yes	Unshrouded seems to be more popular than shrouded.	JST VH
RE	2.54 mm (0.100 in)	1	2	250	30 to 24	No	No	Similar to female "DuPont" connectors and male pin headers. RF series is double row.	JST RE
EH	2.50 mm (0.098 in)	1	3	250	32 to 22	Yes	No	Not 0.1-inch pitch.	JST EH

XH	2.50 mm (0.098 in)	1	3	250	30 to 22	Yes	Yes	Not 0.1-inch pitch. Used by many radio control (R/C) batteries.	JST XH
PA	2.00 mm (0.079 in)	1	3	250	28 to 22	Yes	Yes	Used by FMA Cellpro R/C battery chargers.	JST PA
PH	2.00 mm (0.079 in)	1	2	100	32 to 24	Yes	No	Many stepper motors. Compatible with KR (IDC), KRD (IDC), CR (IDC) series.	JST PH
ZH	1.50 mm (0.059 in)	1	1	50	32 to 26	Yes	No	Compatible with ZR (IDC) and ZM (crimp) series.	JST ZH
GH	1.25 mm (0.049 in)	1	1	50	30 to 26	Yes	Yes	Not 0.05-inch pitch. Sometimes confused with Molex PicoBlade.	JST GH
GHD	1.25 mm (0.049 in)	2	1.25	50	30 to 26	Yes	Yes	Not 0.05-inch pitch. Double row type connector.	JST GHD
SH	1.00 mm (0.039 in)	1	1	50	32 to 28	Yes	No	Compatible with SR (IDC) and SZ (IDC) series.	JST SH
SHD	1.00 mm (0.039 in)	2	1	50	32 to 28	Yes	No	Double row type connector.	JST SHD
NSH	1.00 mm (0.039 in)	1	1	50	32 to 28	Yes	Yes	Lock type connector.	JST NSH
NSHD	1.00 mm (0.039 in)	2	1	50	32 to 28	Yes	Yes	Double row lock type connector.	JST NSHD

Wire-to-wire connectors:
