Terry Lamb, also nicknamed "Baa", is an Australian former rugby league footballer and coach. Lamb played 350 games, with the Western Suburbs (1980–1983) and Canterbury Bankstown (1984–1996). Lamb was known for his support of the ball-carrier - his ability to be in the right place at the right time netted him 164 tries. This earned him the moniker of "The Back-up Man". He also kicked 386 goals and 44 field goals, for 1,442 points in first grade. He played for New South Wales in State of Origin and Australia. Lamb is the only player to appear in every match of a Kangaroo Tour.

Lamb grew up in Chester Hill, a suburb in the Bankstown area and attended Sefton High. He only played in one Grand Final when he filled in for a side above his age group. Lamb is the only International to come from the Chester Hill Hornets club and the ground is now named the Terry Lamb Complex in his honour. He represented Canterbury in junior representative sides, but signed his first professional contract with Western Suburbs Magpies.

On 18 May 1980, Lamb made his first grade premiership debut for Western Suburbs against Balmain Tigers at Lidcombe Oval. Lamb scored two tries in the Magpies' comprehensive 26-4 victory. He scored 9 tries in his debut season and was only just edged out for the inaugural Dally M Rookie of the Year award. Lamb's form in the early stages of the 1981 season was outstanding and he was selected in the NSW State of Origin side. Lamb was called in at the last moment for a very ill Mick Pattison, and only arrived in Brisbane on the day of the match. Lamb met his halves partner, young Parramatta halfback Peter Sterling, for the first time only two hours before kickoff. The Maroons, led by Waaly Lewis and man of the match Chris Close, came back strong in the second half to win 22–15.

The 1982 season was a successful one for Wests and Lamb where Lamb's end of season form caught the eyes of the Australian selectors and he was selected for the 1982 Kangaroo tour. He ruled himself out of the tour as he already planned to marry his partner Kim. The Kangaroos swept all before them on the tour going through undefeated for the first time and becoming known as "The Invincibles". Lamb's final season with Wests was in 1983 where the Magpies won the wooden spoon prize. In spite of this, he was awarded the Dally M Player of the Year Award. Lamb made 88 appearances for Wests, Lamb was later named as halfback in the Western Suburbs Magpies Team of the Eighties.

Lamb settled nicely into Canterbury under the coaching of Warren Ryan and playing outside Steve Mortimer. Lamb's arrival did cause initial controversy when long-serving five-eighth Garry Hughes was dropped to reserve grade in what was to be his final season. Lamb's ability to back up the ball-carrier came to the fore as he was the Sydney Premiership's joint leading tryscorer. with 17. The Bulldogs made the 1984 Grand Final against arch-rivals Parramatta Eels who were looking to win their fourth successive title. Canterbury took out the Grand Final 6 - 4 in a bruising game of football. Lamb was replaced with five minutes remaining due to a nasty gash above his eye.

In 1985, Lamb played 22 games for the Bulldogs, but was forced to miss the 1985 Grand Final due to a groin injury. iMichael Hagan was named as his replacement. Canterbury defeated St. George Dragons 7 - 6 to make it back-to-back titles. 1986 was an eventful year for Lamb. He played much of the opening rounds at halfback with captain Steve Mortimer suspended, and was recalled to the New South Wales State of Origin side. Lamb played in NSW's first State of Origin cleansweep in 1986.

His good form at Canterbury continued with the Bulldogs making a third successive Grand Final, once again playing Parramatta Eels. Lamb was the leading pointscorer for the season, and he would end up scoring 210 points. However, he missed a difficult penalty goal attempt in the final three minutes of the 1986 Grand Final. The Eels won 4–2. Lamb was then selected to go on the the Kangaroo Tour.

Canterbury played the 1988 Grand Final against Balmain, a game which the Bulldogs won 24 -12. As well as scoring a try, Lamb was involved in a first-half tackle, along with Andrew Farrar, which resulted in the concussion of influential Balmain star, Ellery Hanley. Hanley was sent to the head bin, and although he managed to return to the field before half-time, he did not appear fully aware of his surroundings, and was replaced at half-time. Lamb says that there was no malice, and Hanley was not deliberately targeted

One of the first jobs that new coach Chris Anderson did was appoint Lamb as captain ahead of Paul Langmack and Andrew Farrar, who were commonly the deputies when Peter Tunks (who joined Penrith Panthers in 1990) was unavailable. The Bulldogs lost Paul Langmack, Andrew Farrar, David Gillespie and Joe Thomas to Wests under former dual premiership-winning coach Warren Ryan. The club also lost Paul Dunn to Penrith and Jason Alchin to St George. A chronic groin injury would dog Lamb for the next few seasons. Lamb would be a week-to-week proposition throughout the 1990s.

Lamb broke his arm in 1994 when playing his 299th first grade match against Wests. Lamb would return to play his 300th match against Souths at Concord Oval and wearing the No.55 jumper. Concord was only used for three League games and Lamb was a late inclusion in the side.

The 1995 season was to be Lamb's last season and the Bulldogs were keen to send him out a winner, but it all went wrong early when the Bulldogs were caught up in the firing line of the Super League War. Lamb's strength and character as a captain shone through as he held the club together and rallied everyone in the latter half of the season. Canterbury qualified in 6th position for the ARL Finals Series. The Bulldogs defeated St George, Brisbane and defending premiers Canberra to make the Grand Final against Manly.

Canterbury were never troubled in the Grand Final, defeating Manly 17 - 4 in the decider with Lamb potting a crucial drop-goal to give them a seven-point lead. Lamb spent 10 minutes in the sin bin, but that didn't stop his performance as he steered Canterbury to an impressive victory. Due to eratic record keeping, after his retirement it came to light that Terry Lamb was indeed the first player to reach 350 Premiership games.

Terry Lamb played a record 350 first grade games (88 at Western Suburbs, 262 at Canterbury-Bankstown). He also scored 164 first grade tries, a mark bettered only by Andrew Ettingshausen (165), Steve Menzies (180) and Ken Irvine (212). In February 2008, Lamb was named in the list of Australia's 100 Greatest Players (1908–2007) to celebrate the code's centenary year in Australia. He was also awarded an Order of Australia (OAM) for services to rugby league.
